Chapter 14, Problem 22SAE
Summary Introduction
To review:
The two regions involved in the mechanical food breakdown and the need of the process of mechanical breakdown of food in these regions.
Introduction:
Mechanical breakdown of food refers to the physical breakdown of food into smaller fragments. The smaller fragments thus generated increase the surface area of food. It also facilitates the proper action of digestive enzymes on food particles. The two regions that play a considerable role in the mechanical breakdown of food are mouth and stomach.
