Do you know what happens.. to this food inside the body ?

No

Let's get in to the body with the apple and see what happens to it

Wow! we have become so small

We're so small that we can enter the whole body !

So the level starts from mouth

Oh! teeth are making it in to small pieces

and also grinding it

Yes,saliva gets added here to the food !

Food becomes a thin paste

Which way to go now ?

Now there are two ways

One goes to the food pipe

and other goes to the wind pipe

We're going to the food pipe

There's a valve called pharynx

This food pipe is also called esophagus

Oh! now we're entering the stomach

Get ready! there is a lot of liquid here

What's this liquid ?

Oh! these are gastric juices

They make the food merge

is it a kind of boiling ?

Yes this is also called chyme

It is small intestine

Oh! but food is just travelling

Where would the body take nutrients from the food?

Right question at the right time

Most of digestion happens in small intestine

Most of the nutrients are absorbed by body here

What is this green liquid ?

Oh! this is bile

It is produced in liver and pancreas

It helps in digestion

This liquid comes from small intestine

and helps to take nutrients from food

Alright

What are these ?

These are called are villi

Nutrients enter the blood from these villi

Oh! it is a long journey !

Yes it is 22 feet long

Now we are entering large intestine

Is it bigger than small intestine ?

No,small intestine is bigger in length

But large intestine is bigger in width

Oh! small intestine is narrow

That's why it is called small intestine

Yes ,here the water from the food is absorbed

Oh! I want to go back !

Now this is becoming very thick

Yes ,let's go back

Now it is food waste

Which body does not need

It would go out of the body through anus

Here you can see the whole digestive system

Now you know the whole journey of food

Wow! it is a long journey

It starts from mouth

Goes to esophagus

which is food pipe

From there it goes to stomach

Then it enters small intestine

And from small intestine it enters large intestine

And from there it comes out of body through anus

Let's see an experiment on what happens inside the stomach

Oh! what is this ?

Let me show you how gastric juices in stomach ruin the food we eat

Why are you cutting the apple ?

Because food goes in to our stomach in small pieces

What is the liquid in this jar ?

Oh! it is acid so I can not stomach

So acid would burn all the food and give us energy

Yes acid in stomach burns all the food

or we can we say that it cooks all the food to get nutrients

Ya it is taking time

Yes stomach takes 6-7 hours to burn all the food

I want to show you the difference between small and large intestine

Oh! these look like intestines

Look at this .This is very very long

But its mouth is small

It is called small intestine

Yes ,it is 25 feet long

Yes,you are right !

Oh! this with big mouth is called large intestine

It is only 5 feet long

Yes it is small in length but bigger in mouth size

That's why it is called large intestine

What are you doing ?

Oh! I would water some plants with small intestine
