- Multiple Choice
- stomach.
- small intestine.
- esophagus.
- oral cavity.
- pharynx.
Solution
The initial site of both mechanical and chemical digestion is the oral cavity.
Here's why:
-
Mechanical Digestion: This begins in the oral cavity (mouth) where food is broken down into smaller pieces by the process of mastication (chewing). The tongue also helps in this process by manipulating the food.
-
Chemical Digestion: This also begins in the oral cavity. The salivary glands in the mouth secrete saliva which contains an enzyme called salivary amylase. This enzyme begins the process of breaking down complex carbohydrates into simpler sugars.
So, the correct answer is the oral cavity.
