Flashcards in Chapter 3 Deck (11):
1

Mouth

Physical digestion by teeth
Chemical digestion by enzymes in saliva

2

Oesophagus

A tube that carries food from mouth to stomach by muscular contractions called 'peristalsis'

3

Stomach

A muscular sac lined with mucous. Food is mixed with stomach acid (hydrochloric acid) and digestive enzymes

4

Liver

Large organ that produces a green liquid called bile that neutralises stomach acid to help break down food

5

Pancreas

A small sac below the liver. It stores and releases bile into the small intestine

6

Bile duct

Tube like structure which carries the bile from the gall bladder to the duodenum

7

Small intestine

Long thin tube that food moves through after the stomach. Digested food is absorbed from the small intestine bloodstream. More enzymes are produced here to breakdown food further. The blood then transports the nutrients to all body cells

8

Large intestine

Water is reabsorbed back into the bloodstream from undigested food. Passes undigested food to the rectum.

9

Duodenum

The first part of the small intestine. Receives food from the stomach, absorption starts here.

10

Rectum

The lower part of the large intestine, where the undigested food called faeces (poo) is stored before it leaves the body

11

Anus

The muscular opening at the end of the digestive system from which faeces (poo) leaves the body
