The theme of this time is the mystery of the body that we still want to know
Can the things inside the body melt metal?
In fact, 90% of the cotton is real
What is the power of the threat hidden in the sneeze?
Let's find out!
Yes!
Thank you very much!
Today's special lecturer is Professor Katsura Higuchi, a specialist in anatomy,
from the Department of Medical Science and Technology at Bunkyo Gakuin University.
He also gave a talk about the mystery of the body.
Thank you very much!
First of all, let's learn about the problems of our body.
First of all, here.
When you shave your hair, does it get thicker or not?
We'll ask this question.
Which one do you think?
It doesn't get thicker.
It doesn't get thicker?
It doesn't get thicker.
I have the image that it's getting thicker.
My sister shaved her hair and it got thicker.
Your hair?
Don't say that.
Your sister's hair is getting thicker.
I have the image.
That's right.
And then it's cut like this.
If it was growing, it would be loose.
It would be loose, but then it would be cut, so it would look thick.
It would look thick.
What do you think, sensei?
It's sharp.
Akari.
It's sharp.
It's sharp. It's sharp.
I think he just told you about something.
Hair has a cycle.
It comes out again after it's gone.
So it goes back and forth from the hair.
Normally, it's very thin.
And then you cut it like I said before.
The cut section is here.
There are thick parts left.
And the hair slowly pushes up from the bottom.
Until now, the tip was thin, but this time, the cut thick surface will rise as it is, so it will look thicker when it is freshly cut and sprouted.
That's a great answer.
That's right.
It's amazing.
That's right.
However, the hair will change color one day, and when it changes color, it will come out from the root again.
And again, from the root, the tip will be thin and soft, and it will come out.
Let's move on to the next question.
Why does Benkei's crying part hurt?
You know where Benkei's crying part is, right?
Your face looks like a mystery to me.
It's not there. It's here.
It's not here. It's here.
It's really close.
It's totally bearable, Benkei.
Where is it?
It's the cartilage.
It's really painful.
The cartilage is...
Right under the skin,
there is a bone.
It's right there.
Which side of the cartilage is it?
It's the inner side.
When you hit the skin,
you can feel the bone.
The bone is
coated with a membrane
called the cartilage.
The cartilage
is distributed
by the sensory nerves.
The cartilage,
which is sensitive to the pain,
is right under the skin.
So, when you hit here,
the stimulation
is transmitted to the cartilage,
and the sensory stimulation
is transmitted to the cartilage.
Even in the second half of the program, we are still approaching a simple question of the body.
Before the next theme, let's take a look at this video first.
Do you know what this is? This is actually my internal organs.
This is my esophagus.
It's so dirty.
It's dirty. It's clean.
It's clean.
It's stomach.
This is the stomach.
From the narrow space,
from the stomach,
to the esophagus.
I don't need that.
This is my esophagus.
The esophagus.
It's clean.
If you go further, you'll see the colon.
It's so clean.
If you look at it,
it's a triangle.
Compared to the round esophagus, it's a triangle.
This is the colon's characteristic.
It's very beautiful, isn't it?
When I saw it myself, I thought it was beautiful.
What kind of thing happens to the food that enters the body?
Let's find out about the mechanism of surprising digestion.
Here is the surprising truth.
〇〇 melts metal.
〇〇 is the true form of 〇〇.
〇〇 melts metal.
〇〇 〇 〇 〇 〇 〇 〇 〇 〇 〇
〇〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇
First of all, the entrance to eat things, the mouth.
It means that the mouth is amazing, but it means that the digestion has begun from the inside of the mouth.
When you eat something, first of all, you chew it in your mouth.
Chewing means biting and swallowing food with hard teeth.
It is the first step of digestion to make it fine.
Then, when something enters the mouth, it is reflected and saliva comes out.
This saliva also plays a role in digestion.
Do you know how much saliva is secreted in one day?
1 litre.
1 litre? That's a lot.
It depends on the day.
I don't think so.
2 litre.
Both of you are correct.
1 litre to 1.5 litre.
I can't say for sure.
1 litre to 1.5 litre.
Is it your answer?
No, it's not.
Please don't show it.
I want to show it.
It's clean, isn't it?
It's clean inside.
I would like to talk about the roles of saliva.
The first one is eating.
If your mouth is dry, it's hard to chew.
The second one is drinking.
The second one is working to protect teeth and gum.
And the third one is preventing cavities.
Preventing cavities.
This is because it contains a lot of saliva.
The bacteria in the cavities make a acid in the mouth and melt the teeth.
The role of saliva is to neutralize the acid.
The bacteria in the mouth and melt the teeth. The role of saliva is to neutralize the acid.
Let's talk about the model of the esophagus.
It enters from the mouth and goes through the throat.
The esophagus is about 25 cm long.
It goes through the throat from the mouth and carries it now.
The amazing thing about the esophagus is that it can be swallowed even if you stand upside down.
This is only for people who have trained.
I don't know if it's true, but I'd like to do an experiment.
Mr. Suchi, can I ask you a favor?
I'm not training.
Let's start the experiment.
It's not good to drink alcohol.
Please drink coke with your head down.
It's still hard.
I want to drink it while sleeping.
Please drink it while it's cold.
Wait a minute.
It's impossible.
I'm sorry.
It's okay.
It's the last time.
You are drinking it.
It's decreasing, isn't it?
But it's hard.
It's getting more and more.
It's just that it's hard to drink.
It's hard.
It's because it comes in here.
But you can drink it in this state, right?
Even in this state, it's refreshing.
As expected, it's cola.
I wonder why things can be swallowed upside down.
The esophagus is not just an esophagus.
It doesn't flow from the top like a rain shower.
It's a muscle esophagus.
Is it an esophagus?
That's right.
It's usually closed except when food goes through.
I prepared a rice ball here.
This is a stocking.
It's the one you wore today.
If it's a stocking that's been a little
There is a stocking that has been a little.
I'm sorry.
This is the movement I just said.
It's called a forward movement.
It's like this.
The rice ball comes in from the mouth and goes through the esophagus.
It goes through here.
At that time, it's like this.
Hold it where you press the rice ball.
It's like this.
It goes through the esophagus.
Even if it's the opposite direction, it goes like this.
So even if you stand upside down, you can drink it.
After drinking and passing through the dining hall, you will reach the stomach.
The stomach is amazing here.
The stomach is a bag that stores food.
It's a bag for storing food.
Isn't that part of digestion?
Digestion of course.
save up?
You're going to have to save it.
Do you know how much time you can save?
4 hours.
Somehow.
I thought about breakfast, lunch and dinner.
13 hours.
13 hours?
I read it somewhere.
Oh, really? That's a very powerful theory.
Sensei, how many hours is it?
It's pretty sharp. It's about 4 hours.
How many times did you read it?
It's strange.
During that time, your stomach will be muddy.
It will change to a muddy substance like porridge.
Your stomach will be full, right?
But I can still eat something sweet.
Women really eat that after they are full.
If you show your favorite food even though you are full, your appetite will be stimulated.
It's the result of being stimulated.
It's the same as eating a lot of rice when I ate Nasubi's nukazuke.
You can use that.
I think there are many things that stimulate your appetite.
I used to be an idol.
This is what happens when you take a step forward.
Even if your stomach is full, when the stimulation from the brain comes from the appetite, the stomach exercise becomes active.
And send the contents to the intestines as soon as possible to create space.
That is called a separate stomach.
That is how it is explained.
I want to eat, so I open it.
The food is not rotten.
The temperature inside the stomach is about 37 degrees because it is a body temperature.
What happens if you put food at 37 degrees Celsius for 4 hours?
There is no such thing as a burp smelling putrid, right? So, those bacteria are in a state where it is difficult for them to multiply in the stomach, especially in the stomach. The reason for this is the function of gastric juice.
If the liquid that dissolves this metal also has a function, that's what it means.
Let's take a look at the shocking video of melting metal
First of all, the experiment to melt the metal
I would like to put this meat on the artificially made liquid.
There is a enzyme that dissolves protein in the liquid.
I put the enzyme in it, so it's a little cloudy.
It's an enzyme.
Yes, I'll hang the meat on the string like this.
It's been 40 minutes.
It's a little cloudy, but you can see that it's getting a little softer.
Let's pull this up a little.
It's been about 60 minutes.
It was a solid piece of meat, but now it's melting.
It's a solid piece of meat.
This is how the liquid works.
Normally, this is how protein is disassembled into meat.
This time, it's the same ingredient, but the enzyme of the protein is a little disassembled.
Other ingredients are adjusted in the same way as the liquid.
Put it in there.
If you do this, bubbles will immediately form and it will start to melt.
This state is a state of acid that melts metal.
There is acid in it.
If you look at it for 20 to 25 minutes, it gets smaller as you look at it.
It's faster than meat.
After about 30 minutes, the metal will fall off the string.
After about 35 minutes, there is no trace.
It's a hard metal called magnesium, but it melts like this.
This is the acid that comes out of the stomach.
This is the enzyme that breaks down the protein.
This is mixed and comes out.
Even if you eat iron by mistake, you don't have to be in a hurry.
If you drink a nail, that's it.
You should be in a hurry.
But if it's that strong, the stomach itself is going to go crazy.
There is an enzyme that protects the stomach wall.
The coating of this enzyme will prevent your body from melting.
However, if the barrier function of the stomach weakens, it will be like this.
There is a word that is often used.
This means that the stomach wall has been corroded by the enzyme.
That's stress, isn't it?
That's why the barrier function is weak.
Or it can lead to a severe miscarriage.
What if there is a hole?
If it gets worse.
That's why I want to go to the hospital before that happens.
It's just a heavy story.
When my father had a miscarriage,
he had a stomach ulcer.
When he came home, he collapsed.
He was in the hospital for 3 months.
What are you talking about?
What were you trying to do?
I remembered my dad.
I was very stressed.
What's wrong with you?
He is kind.
I'm about to cry.
Next, I wonder if there is a deep relationship between the thread and the geppu that comes out often after eating.
This is a picture of the stomach in the state where it was taken out earlier, but there is a part called the stomach in the upper part of the stomach.
The air is accumulated here. The ceiling is inflated like a dome. The air comes out of what is accumulated here.
The air is accumulated here.
It was coke before, but in the case of coke, carbonic acid gas comes out.
The air is absorbed with food.
The air that is absorbed is accumulated in this high place.
If you can't hold it here, the entrance will loosen and come out.
Is it true that people who eat fast are easy to gain weight?
It is said that it is better to chew well and eat slowly.
This is because the stomach swells and you can get a sense of fulfillment.
In this way, the time until the stimulation of the stomach to swell is transmitted to the brain is quite long, and the time until the stimulation of the stomach to swell is transmitted to the brain is quite long.
It is not transmitted immediately.
So, before the stimulation of the stomach to the brain is transmitted,
if you eat it quickly, you can get a sense of fulfillment.
But, it is not possible to stop there.
I see.
It means the time difference.
Yes.
So, you should eat slowly.
Of course, chewing well,
the stimulation of chewing is transmitted to the brain,
and there is a theory that it works to get a sense of fulfillment.
I see.
So, eating slowly, chewing well,
is one of the secrets of not getting fat.
Shochou is the part of the stomach that is filled with ides.
There is also something amazing about this butterfly.
Shochou is the part of the stomach that is filled with ides.
Let's take a look at the amazing part of shochou.
How big is the surface area of shochou?
It's the third largest in the world.
It's the third largest in the world?
You can't answer that.
It's the third largest in the world?
Let's talk about the length first.
The length is about 5 to 6 meters.
There was a person from worldwide.
It's actually about this much.
There was a person from worldwide.
It's the third largest in the world.
It's about 6 meters long.
It's about this much.
Are you angry?
What are you doing?
I used to do it.
I'm sorry.
It's amazing.
You can draw 1000 newspapers for one tennis court.
It's the surface area inside.
It's very big.
I'd like you to take a look at the surface area of the shochou with an electronic microscope.
The shochou has a surface area of one tennis court.
There's a way to make the surface area wider.
As you can see, there's a lot of ids.
To make it even wider, there's a small id like the surface of a towel.
It's called izumou.
If you look at it with a microscope, there's a lot of ids like this.
Let's make it even wider.
This is the cell of the shochou's id.
There's a lot of ids on the surface of the cell.
If you extend the ida, izumou, and ids of each cell,
the surface area will be more than 200 square meters.
This is called izumou.
This is to make the surface area wider, touch the ids, and absorb them.
The shochou is a place where ids are digested and absorbed in earnest.
At the beginning of the shochou, there's a part called izumou.
I'll show you with my stomach.
This is the ida.
This is the shochou.
The part that connects the ida to the shochou is near the back.
This is it.
This is the izumou.
It's about 12 fingers long.
It's called the izumou.
There's a part that connects the izumou to the shochou.
It's called the izumou.
If you look at the back of the izumou,
there's something fluffy.
It's an amazing organ.
The water sculpture here is amazing. It secretes the strongest digestive fluid, water fluid.
The water secreted by the 12 municipalities is called the liquid produced by the water sculpture. It's a digestive juice that contains a concept. In the 12 cities and towns, something called water will come out. This water solution is starchy, so-called carbohydrate rice or bread. Meat as before
Then there is the oil content, which breaks down all the various nutrients contained in these foods, It's all round when it's broken down to the level of tiny molecules that can be absorbed into the body. Conversely, if this part becomes ill, it will be a serious problem. As I said earlier, the water sculpture is already in the back of the body.
It's a painful place, isn't it? If you think it's a back pain and think it's a water statue, there are many people who drink alcohol. I'm suppressing my shins.
I didn't care
I don't care about your water flame
The decomposed food is finally transported to the large intestine. What will happen in the large intestine?
In the small intestine, as I said earlier, most of the nutrients are absorbed. In the large intestine, it is not the time to absorb nutrients, but the last remaining water.
It is a place that absorbs the water left in the contents and forms a lump-like vein.
Let's take a look at the amazing part of the large intestine.
About 10% of the intestine is edible.
What is the rest?
About 90% of the intestine is edible.
What's wrong, Kinoshita?
I heard it's red.
Red?
It's like the red of an elephant's stomach.
Red?
It's red.
Is it red because it's dirty?
Can you do it?
It's pretty sharp.
I've been talking to the owner of the old shop who I know for a long time.
There are too many things, so it's a little confusing.
Actually, this is a little bit of unripe persimmon.
It's a little bit red, but it's a persimmon that has been peeled off.
This kind of thing will be reborn.
It will be reborn more and more.
This is the residue.
Or the bacteria in the intestines.
The bacteria in the stomach.
This is the remaining 90%.
It's a big part.
So even if you don't eat rice, it will come out, right?
I don't know if the unripe persimmon will basically disappear.
The cells in the body are reborn.
The cells in the intestines will also be reborn on the 2nd.
It is gradually happening that it is born and dies.
Even if you don't eat this flight, even if you take out one or two meals, it will come out.
By the way, if you exercise after eating, your stomach will be like this.
This is also the cause of indigestion, isn't it?
There are various theories, but one interpretation is that if you look at indigestion, it goes up, goes to the side, and goes down again.
Then you can have a corner like this.
In this corner, for example, after eating, the contents are sent here, and when it is shaken, gas accumulates from the inside and accumulates in the corner.
Then, the pressure inside becomes higher, the stomach swells, and it hurts.
That's why there are cases where it hurts from the side, and there are cases where it hurts from the side.
There are various other theories, but one reason is that there is so-called indigestion.
The questions of the body that you want to know.
In the second half, I'm still worried about 〇〇.
What happens when you put up with 〇〇?
I've heard of this.
It's going to be 〇〇.
〇〇?
When I do 〇〇, I drink a lot of 〇〇.
If you say that to someone, it will be 〇〇.
What? You say 〇〇 and 〇〇?
No way!
The air?
The air.
From which side?
From the one who is relaxed.
From the one who is relaxed?
The one who is relaxed.
You say 〇〇 and 〇〇?
It's an interesting answer.
Actually, it is 〇〇.
What?
So, it's 〇〇?
No, it's not.
It's 〇〇.
〇〇. 〇〇. 〇〇. 〇〇.
It's not like that.
The gas is absorbed by the intestine wall.
Gas is also absorbed?
Gas is also absorbed.
You have to be able to do it.
You can't just leave it as it is.
Gas is also absorbed by the intestine wall.
It comes out as a breath from the lungs.
Doesn't it smell like that?
It's not necessarily smelly.
It doesn't come out directly as it is.
It goes through the liver where it detoxifies and discharges various chemical substances.
It doesn't come out 100% as it is.
It doesn't come out of the lungs.
It comes out as a breath from the lungs.
Does it smell when you look at the sun?
Do you get it, Rika-chan?
I get it.
I get it too.
I get it.
Is it that little?
First of all, I was told not to look at the sun.
I was told.
I was told because it would be a nuisance.
But if you look at it, there's something, right?
If you look at it, you'll be surprised.
Really?
It doesn't work for sneezing.
Teacher, how about this?
This is also a phenomenon.
It has a name.
It's called light sneezing reflection.
There is a reflection of sneezing.
Sneezing is in the back of the nose.
If you're stimulated by that, you'll sneeze.
It's a reaction of the body trying to spit out what's in the nose.
Even in strong light, the sensory nerves of the eyes and nose go to similar places.
It's thought to lead to sneezing.
So when you sneeze, you look at the lights.
I see it.
I thought everyone was thinking the same thing.
Not at all.
My dad sneezes when he goes to the toilet.
That's funny.
The power of sneezing is amazing.
As I said before, you have to blow it out.
You have to blow it out with a certain pressure.
Mr. Nakagawa will do an experiment on the power of sneezing.
With this machine that can measure the momentary wind, let's measure the power of Mr. Nakagawa's sneezing.
First of all, let's breathe normally.
There is a graph, but it is a gentle wave when breathing normally.
It's not such a big wave, is it?
This is breathing normally, isn't it?
Let's measure it.
The speed at the highest point of this mountain.
That's right. The lung was around there.
It moved a little.
It's about 5 km per hour.
Breathing at a very slow speed of 5.5 km per hour.
Next, let's take a look at this.
Would you like me to cough? Shall we try again?
Is it about the same?
Well then, let's go to this high place around here.
And the speed of the seat is 59 km, 60 km.
This is about the speed of a car.
Well, even a simple seat is about this.
It's a lot of power here, isn't it?
Next, I'd like you to stimulate your nose and sneeze.
I see.
Is it going to be 100 km?
It's funny to see people's faces when they're doing this.
It's a little blurry, isn't it?
It's amazing.
It's amazing, isn't it?
Let's measure it.
Wow, it's amazing.
It's fast.
I can't do it like this except for the major league.
It's just a momentary speed.
I want to add 200kg.
Do your best.
Can I add 200kg?
Yamauchi, you do it, and I'll go to the one that seems to come out.
I see.
By the way, the face when I was stolen.
I don't have it.
I left it here.
I don't have it.
You can do it.
What kind of state is this?
By the way, Mr. Kawata, have you seen 200 so far?
No, I haven't.
No, you haven't seen 200.
It's a world record.
I...
No no no no
I'll take too
Let me take too
This is the only one
How is it?
If time works out, say something
Wow
Amazing
Let's read it
Is it printing out?
Ahhhhh!
It's coming out!
I can get 200 points!
Wait, it's going to go in everywhere.
It's coming out!
I can't get it!
It's coming out!
The mission of this time is to climb the rock wall to reach a higher place
The three of them will be challenged by rock climbing
They will climb the rock wall to reach the idol's height
They will climb the three-stage rock wall of Shirahama
The height is about 15 meters
Members who can climb the three-stage rock wall will be rewarded with Shirahama's specialty high- class fish kue-cooked food
Three people who practiced in the gym and tasted the height of the rock wall
Can they climb the 15-meter rock wall?
They will climb the 15-meter rock wall
If you want to give up on the way, where is the easiest place to give up?
It's like a point to give up.
A point to give up?
Giving up is easy now.
I'll do my best.
Finally, it's time for the main event.
The top batter is Kanakichi, who is the most stable.
At first, Kanakichi has to move to the side.
Yes, that's it.
This one?
Please move to the side.
It's scary.
It's scary already.
She cleared the first obstacle and continued to climb after that.
You did half of it, right?
Half of it.
You did half of it.
She has reached the midpoint.
If you look at this, it's over.
From here, the hard rock skin that can only be put on the toes of the feet continues.
Do your best!
No, it's scary.
If you go there, you can rest assured.
The last difficult part is that you have to raise your body with the power of your arms.
Where is it?
Up there! Up there!
This is scary.
It's amazing.
Successfully cleared.
It's amazing.
We did it.
Amazing.
Congratulations.
We did it.
Even if a little thing happens, I'll be fine.
Next, Airi, who was the worst at climbing in practice.
First of all, the first challenge.
Cool.
It's like a commercial for a nutritional drink.
I know.
A lot of fights.
No, it's low.
This is scary.
Good luck.
You can do it.
She's going crazy.
She has a high tension.
And she takes Airi to the top safely.
I've been climbing trees for a long time.
I think so too.
I've been climbing trees for a long time.
My hands and feet move naturally.
I'm glad.
Shuu is the most afraid of the last.
Will she be able to climb all the way to the top?
I'm always bad at Manabu-kun's location.
I'll do my best this year.
The first point is that I was watching the two of them climb, so it was surprisingly easy to clear.
Oh, it's hard from here. I think it's better to choke a little.
I'll give you a lot more on the left foot.
The place where the mark is written.
A little more in the middle.
Dangerous.
Wait a minute.
Shu, who is afraid of heights, does not want to look down, so it is difficult to confirm the foothold.
Calm down.
It's scary.
What about the right foot?
She's struggling with the second obstacle.
It's hard to climb.
What should I do?
Put your foot on your waist.
Put your left foot on your waist.
With the advice of the teacher, she finally climbs.
She needs the strength of her arms.
To the last obstacle.
That's the only way.
It's too hard.
You can do it!
Go! Go!
You can do it!
She did it!
It's so hard!
You can do it!
Oh, my God!
I can't watch it!
She did it!
I was frustrated because I was looking down and I was shouting.
I went up and did it.
She did it!
It feels good!
The three of them arrived at the top of Shumo and succeeded.
So, they went to the store to eat the reward of kue.
First of all, the fresh kue they caught on this day.
It has a soft texture.
Really?
It has a soft texture.
Kue ate it.
Kue ate mine.
What are you talking about?
What do you want to do?
You can't comment on it.
Next,
It's so good!
It's just the right timing, isn't it?
It's so good!
It's so fluffy
It's so soft
It's really delicious
It's not over-cooked
The soup is soaked in
It's really delicious
Amazing!
That's amazing.
What is this?
Why is this pose?
Is this during a gag?
I imagined a bee because it's a canter.
That's true.
What is this?
Amazing.
I was eaten by a
You said something like a dictionary.
What is this?
I don't remember.
You don't remember?
It's scary.
That's scary.
I don't remember.
KASHIKO was good, but not good at all.
Let's announce the winner.
