C.Teeth
D.Pharynx
E.Salivary gland
Choose the correct answer from the options given below :

• A. mouth, teeth, tongue, salivary gland, pharynx
• B. mouth, tongue, teeth, salivary gland, pharynx
• C. mouth, tongue, salivary gland, teeth, pharynx
• D. mouth, salivary gland, teeth, tongue, pharynx

Hint:

Digestion starts in the mouth where teeth, tongue, and saliva work together to process food before swallowing.

Answer 1

The Correct Option is A

Concept: The digestive process begins in the mouth where food is mechanically and chemically processed. Different organs in the oral cavity perform specific functions:
• Teeth break food into smaller pieces.
• Tongue mixes food and helps in swallowing.
• Salivary glands secrete saliva containing digestive enzymes.
• Pharynx helps in passing food from the mouth to the esophagus.

Step 1: Identify the sequence of food processing.
Food first enters the mouth where teeth chew it.

Step 2: Determine the correct order of organs involved.
After chewing, the tongue mixes food with saliva secreted by salivary glands, and then food passes into the pharynx. Thus, the correct sequence is: \[ \text{Mouth} \rightarrow \text{Teeth} \rightarrow \text{Tongue} \rightarrow \text{Salivary gland} \rightarrow \text{Pharynx} \] Hence, the correct answer is: \[ \boxed{(A)} \]
