The Digestive System
The digestive system is what a human uses to eat. Food comes in through our mouth is broken down in our stomach and our body takes the food in through the intestines. Then the waste goes out through the anus.
The digestive system is made of many organs. Here are some of the organs and their functions:
- Oesophagus - Pushes food down into the stomach.
- Stomach - Breaks down complex sugar by acid.
- Liver - Makes a thing called bile that breaks down fat.
- Gall bladder - Stores the bile and adds it when needed to the small intestine.
- Pancreas - Makes chemicals that break down food.
- Small intestine - Absorbs food for body.
- Large intestine - Absorbs water and salt.
- Rectum - Stores waste.
- Vermiform Appendix - Vestigial organ (has no function in human body).
