1

Mouth

The mouth is the first part to the digestive track. It chops and grinds down foods into small pieces. Saliva produced from glands under the tongue helps to break down the food, and mucus makes it easier for the food to go down the oesophagus

2

Oesophagus

Muscle contractions push the food down to the stomach. These contractions are so strong that they work upside down

3

Stomach

Food enters into the stomach through a ring called the sphincter. The stomach churns up the food into a liquid called chyme. Stomach acids kill the bacteria on the food

4

Liver

"Same as Gall Bladder"

5

Gall Bladder

Liquid in the gall bladder is called bile. Bile goes into the small intestine to break down the fats in foods so they can mix with watery liquids. "Emulsification"

6

Pancreas

Releases hormones which control glucose levels in your blood. When blood sugar drop insulin secretion is replaced by glucagon, which converts glycogen back into glucose.After eating insulin is released, which puts excess glucose to convert into glycogen for storage in the liver

7

Small Intestine

Food carries on moving through the small intestine by peristalsis. The small intestine is made up of the duodenum and ileum. Bile enters the duodenum after eating and breaks up the fats into tiny droplets ready for lipase to break it down into smaller substances

8

Large Intestine

Made up of the colon, appendix and rectum. By the time it gets to the colon, digestible foods have been broken down and absorbed into the blood. Only indigestible material and water remains. The colon absorbs water into the blood and undigested material gets more solid. Semi solid material (faeces) collects in the rectum and leaves via the anus
