Nutrition and Digestion

The process of consuming nutrients to utilize them for various biological purposes is known as nutrition. The substances absorbed from food are known as nutrients. They serve different important functions in the body, such as repairing wounds and damages, generating energy for metabolism, and regulating biochemical reactions.
