Question

what do you mean by digestion

Answer 1

Digestion refers to the breakdown of food into smaller components that can be absorbed into the bloodstream. This digestion or catabolism is divided into two types – the mechanical digestion of food that occurs in the mouth when it is physically broken up into smaller pieces and the chemical digestion that occurs in the gastrointestinal tract when the food is broken down into small molecules by digestive enzymes.

In mammals, digestion involves the intake of food through the mouth where it is chewed between the teeth in a process called mastication. The saliva present in the mouth contains amylase which begins the break down of starch in the food.
