Explanation
Digestion is a complex process that involves the breakdown of food we eat into nutrients, which the body uses for energy, growth, and cell repair. When you eat foods -- such as bread, meat, and vegetables -- they must be broken down into nutrients in a process called digestion. Digestion begins in the mouth, where food is busted up by the teeth into bits and coated in enzymes secreted into the saliva. The main role of digestion is to convert complex foods into simpler molecules that can be absorbed by the cells of the body and used in metabolism. Our body doesn't sweat or fight off diseases through digestion. It also doesn't transport oxygen or remove toxins from the blood. Therefore, the main role of digestion in our body is to break down food molecules into simpler forms that can be absorbed by our body for its functioning.
