Question 8

Digestive system

Answer 8

Mouth = mechanical and chemical digestion, where the food enters + Sal airy glands produce amylase (starch to glucose conversion)
Oesophagus = tube which moves food from mouth to stomach
Stomach = acidic PH to kill bacteria + pepsin
Pancreas = Digestive enzymes
Liver = production of bile - aids digestion - alkali PH = optimum for bile
Gall bladder = bile storage + releases into duodenum
Duodenum = food + digestive enzymes mix
Ileum = food absorbed into blood
Large intestine = water reabsorption
