Which of the Following Best Describes the Chewing of Food

Question

Which of the following best describes the chewing of food?
A) Emulsification
B) Mechanical digestion
C) Peristalsis
D) Absorption

Accepted Answer

Chewing, also known as mastication, is a process of mechanical digestion where food is crushed and broken down into smaller pieces by the teeth and jaw muscles. This facilitates better mixing with digestive enzymes and increases the surface area for further chemical digestion. Therefore, option B, mechanical digestion, is the best choice to describe the chewing of food.
