Q

explain how protein is digested in the stomach and SI

A

food mixed with pepsin (enzyme that aids protein digestion) and hydrochloric acid (helps to break down solid particles)

enzymatic degradation of protein by protease (pancreatic secretion)

17
Q

explain how fibre is digested in the caecum and absorbed in colon

A

plant material broken down by the microbial population. Fibre is converted to VFA and the passed into the colon where absorbed.

18
Q

explain how starch is digested in SI

A

enzymatic degradation of starch by amylase (pancreatic secretion)

19
Q

explain how sugar is digested in SI

A

amylase

20
Q

explain how fats are digested in SI

A

bile released from the liver emulsifies fats and stimulates lipase secretion from the pancreas. Enzymatic degradation of fat/oil by lipase

21
Q

capacity of stomach, SI and LI

A

stomach (18L)
SM (55-70L)
LI (86L)
