Detailed explanation-1: -Digestion is the mechanical and chemical break down of food into small organic fragments. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across the digestive epithelium.
Detailed explanation-2: -During chemical digestion, your food is broken down into very small pieces that your cells can absorb. Your cells will use the nutrients available from chemical digestion to make energy and new cells. This process is called metabolism.
Detailed explanation-3: -The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.
