Our digestive system helps us get the nutrients we need from our food.

Mouth

Eating

Esophagus

When we eat, food goes in our mouth then down the esophagus.

1. The mouth has teeth that break down food into small pieces and a tongue that mixes the food with saliva so that it's easy to swallow. 2. The esophagus is a long tube. Food goes down here to the stomach.

Stomach

Stomach

After the food goes down the esophagus, it comes here.

3. The stomach is like a bag. The food stays here for about three hours. Gastric juices break down the food even more and turn it into a thick liquid. The thick liquid leaves the stomach and goes into the small intestine.

Gastic Juices

Intestines

Large intestine

After the food breaks down in the stomach it passes through the small intestine then the large intestine and leaves the body through the anus.

Small intestine

4. The small intestine is a very long thin tube. There are lots of blood vessels around the tube. The thick liquid from the stomach goes through here and the nutrients pass into the blood. 5. The large intestine is a wide tube. It connects to the anus. What our body doesn't need goes along here and out through the anus when we go to the toilet.
