Digestive system

Digestive system explanation
wk 4

The digestive system is the way our body breaks down food to get all the energy out for us to use. The rest is passed out as waste.

The first part of the digestive system is the mouth. The saliva does only one job, it breaks down the food so that we can swallow it. We can get energy from food.
In the stomach the food break down until it look like liquid.

After that the liquid goes in the small intestine  bile and more gastric juice then take out protein fat and carbohydrates for the body to use.

Then the left over goes into the large intestine two thing are taken out is salt and water the rest become poo.
