Answer 2

Ingestion, Digestion and Absorption these are life processes of human beings:

• Ingestion: Ingestion is when food is taken into our mouth. It is the first step involved in the process of digestion in humans.

• During ingestion our teeth help break down the food and our salivary glands produce salivary amylase so that the starch can be converted into maltose simple sugars. Our tongue helps us to taste this food which we eat during the process of ingestion.

• Digestion: Digestion is the process of breaking down the food so that it can be easily absorbed by the body.

• Digestion happens thoroughly in the stomach and small intestine.

• Absorption: Absorption this is the process by which digested food is absorbed by our body so it can be utilized for different uses  like making energy storing as fats etc.

• Absorption is takes place in the small intestine there is many finger like projections called villi which increases the surface area for the absorption of digested food.
