Let's Talk About Mechanical Digestion!

What is mechanical digestion?

A. Breaking down food using enzymes
B. Breaking down food using acid
C. Breaking down food into small particles using a mechanical grinder or food processor

Answer:

The term for the physical breakdown of food into smaller pieces, initiated in the mouth and continuing in the stomach, is mechanical digestion.

Explanation: When you eat an apple, the process it undergoes first in your mouth is known as mechanical digestion. This is the physical breakdown of chunks of food into smaller pieces by various organs in the digestive system, particularly the mouth and stomach. In the mouth, your teeth, especially the molars, and your tongue play crucial roles in this process. Molars, having broad and flat tops, are well suited for crushing and grinding food into smaller particles. Mechanical digestion is significant because it increases the surface area of the food, allowing enzymes to later perform chemical digestion more effectively. The mechanical process is purely physical and does not chemically change the food; instead, it prepares the food for further digestion and absorption in the body. Mechanical grinders or food processors are tools that mimic the action of mechanical digestion, reducing food to small particles outside of the body for various purposes, such as cooking or processing.
