Question

What is Mechanical Digestion and where does it happen? (Must be a minimum of 3 sentences)(4 points)

Answer 1

Mechanical digestion is the process by which food is physically broken down into smaller pieces without altering its chemical structure. This process begins in the mouth, where teeth chew food into smaller fragments, making it easier to swallow and increasing the surface area for enzymes to act upon during chemical digestion. Mechanical digestion continues in the stomach, where the muscular contractions mix and churn food, further aiding in its breakdown before it moves into the intestines for further digestion and absorption.
