Mechanical Digestion

Description

Mechanical digestion is the physical process of breaking down food into smaller pieces without changing its chemical structure. This process increases the surface area of food, making it easier for enzymes to act during chemical digestion.

Key points:

• Method: Involves chewing with teeth, grinding in the stomach, and churning or mixing in the intestines.
• Purpose: Facilitates easier swallowing and more efficient chemical digestion.
• Location: Begins in the mouth (teeth and tongue), continues in the stomach and small intestine through muscular movements.
