The Digestive System
The digestive system is a long track of organs. It starts in the mouth and and ends in the anus. Your food is energy and your body absorbs it. It is vital to our body because otherwise we can’t break down food and we won't have any energy in our bodies.
In your mouth, your teeth are crunching and munching your food and your saliva kicks in to help with breaking down your food into small tiny pieces. Then it goes down the oesophagus.
The oesophagus is a muscular tube that's about half a metre long. It pushes your food down to your stomach.
In your stomach, you food it churned and mooshed even more it has an acid called Hydrochloric acid that is harmful to your skin. There is a stomach lining that protects vital organs from the acid. Your food stays in your stomach for 3-4 hours.
After you food is churned up, it goes into the small intestine. Its funny because it is 6-7 metres long! It has little finger things called villi, they absorb all of the nutrients and water. Now your food should be solid and brown. Next is your large intestine.
Your large intestine is only 1 metre long! It is called the large intestine because it is wide. The small intestine might be long but it is narrow. At the last part of the large intestine, the rectum, it waits for a bit then… You're ready to go to the toilet!
The Digestive system is a vital part of our lives. Eat healthy food so The Digestive System is always in good health!
