Your body needs food to help it grow. Food also gives you energy. But your body cannot use the food you eat just as it is. Food has to be changed so that it can be used by the body.
The digestive system changes food by breaking it down into tiny particles. This process is called digestion.
The stomach and the intestines digest the food. They are the main organs of the digestive system. Digested food particles pass from the intestine into the blood and are carried to all parts of the body.

.The food we eat must be digested so that the body can use it

Questions

 

1) Why do we need food?
2) Why must food be digested?
3) How does the stomach help digestion?
4) What happens to food in the intestines?
5) How does the digested food reach all parts of the body?

1: Your teeth chew and chop up the food into smaller pieces that we can swallow. Digestive juices in saliva start digesting food. 2: The food we swallow is pushed down a tube called the gullet and into the stomach. 3: Inside the stomach the food mixes with digestive juices that turn the food into a thick liquid similar to porridge. 4: The intestines break down the food even more until the food particles are small enough to move into the blood. 5: Any undigested bits of food that your body can't use are pushed out of the end of the intestines when you go to the toilet.
