Flashcards in Chapter 3 Deck (11):
Physical digestion by teeth
Chemical digestion by enzymes in saliva
A tube that carries food from mouth to stomach by muscular contractions called 'peristalsis'
A muscular sac lined with mucous. Food is mixed with stomach acid (hydrochloric acid) and digestive enzymes
Large organ that produces a green liquid called bile that neutralises stomach acid to help break down food
A small sac below the liver. It stores and releases bile into the small intestine
Tube like structure which carries the bile from the gall bladder to the duodenum
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
Water is reabsorbed back into the bloodstream from undigested food. Passes undigested food to the rectum.
The first part of the small intestine. Receives food from the stomach, absorption starts here.
The lower part of the large intestine, where the undigested food called faeces (poo) is stored before it leaves the body
