Question

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

Answer 1

Mechanical digestion refers to the physical process of breaking down food into smaller pieces without altering its chemical structure. This process primarily occurs in the mouth, where teeth chew food, and in the stomach, where muscular contractions churn and mix the food with gastric juices. Additionally, mechanical digestion aids in increasing the surface area of food, making it easier for enzymes to chemically break down nutrients in the subsequent stages of digestion.
