Key Stage 2
Meaning
The digestive system is the parts of the body that we use to get nutrients out of our food.
About The Digestive System
- The digestive system breaks food down into small pieces.
- The small pieces can then be absorbed into the body.
- The bits the body does not need leave the body as faeces.
- The digestive system is made up of several parts:
Key Stage 3
Meaning
The digestive system is an organ system that breaks down food for absorption into the blood.
About The Digestive System
- The digestive system breaks down food mechanically and chemically before absorbing nutrients into the blood.
- The digestive system takes large insoluble molecules and breaks them down into small soluble molecules to be absorbed.
There are several organs in the digestive system you should know:
The mouth is an organ is used to start digestion of food. | The oesophagus is an organ that connects the mouth to the stomach. | The stomach is an organ that digests food. |
In the digestive system the liver produces bile which neutralises the acid from the stomach and helps break down fat. | In the digestive system the pancreas produces enzymes to chemically break down food. |
