❥ The food we eat cannot be digested by our  body directly.

❥ It needs to be broken down into  substances which can be easily absorbed  by the body.

❥ The process of breaking down the food into  simple form is called digestion.

1. ${\underline{\boxed{\mathrm{Mouth:-}}}$

Digestion begins in the mouth. Our teeth  chew and break the food into smaller pieces. Saliva  makes the food softer and easy to swallow.

2. ${\underline{\boxed{\mathrm{Food\:Pipe:-}}}$

The soft chewed food is passed down  the down the food pipe to the stomach.

3. ${\underline{\boxed{\mathrm{Stomach:-}}}$

Digestive juice are present in the  stomach. These help to digest food while stomach  muscles churn it well.

4. ${\underline{\boxed{\mathrm{Liver:-}}}$

It produces juices that play an important role  in the digestion of food.

5. ${\underline{\boxed{\mathrm{Small\:Intestine:-}}}$

It is a long coiled tube. The food  passed from stomach is further digested here.The  digested food is in the liquid form and the nutrients  are absorbed into the blood from the walls of this  organ. The blood carries these nutrients to various  parts of the body.

6. ${\underline{\boxed{\mathrm{Large\:Intestine:-}}}$

Fibres cannot be absorbed by the  body. They are passed as undigested food into the  large intestine. Its blood vessels absorb excess water,  store and throw out the undigested semi-solid waste  from the body through the anus.
