Question

Examlex · Accepted Answer

The Answer is a) Mouth: In the mouth, the major digestive events include mechanical digestion through the process of chewing, and chemical digestion through the action of salivary amylase, which breaks down carbohydrates into simpler sugars.

b) Stomach: In the stomach, the major digestive events include the mixing and churning of food with gastric juices, which contain hydrochloric acid and pepsin. This helps to break down proteins and kill bacteria present in the food.

c) Small Intestine: In the small intestine, the major digestive events include the further breakdown of food through the action of enzymes from the pancreas, liver, and the intestinal wall. This is where most of the nutrients from the food are absorbed into the bloodstream.

d) Large Intestine: In the large intestine, the major digestive events include the absorption of water and electrolytes from the remaining indigestible food material, and the formation and elimination of feces. The large intestine also contains beneficial bacteria that help in the fermentation of undigested carbohydrates and the production of certain vitamins.
