Key Stage 2

Meaning

A diagram of the digestive system.

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

A diagram of the digestive system.

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:

These are all human organs which may look different in different mammals.

Oesophagus.png
Stomach.png
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.
Liver.png

Intestines.png
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.
