Question

The passage of Air in Respiratory system is : \[ \begin{aligned} A.&\ \text{Oral cavity} B.&\ \text{Trachea} C.&\ \text{Pharynx} D.&\ \text{Larynx} E.&\ \text{Lungs} \end{aligned} \] Choose the correct answer from the options given below :

• A. A, D, C, B, E
• B. A, B, D, C, E
• C. A, C, D, B, E
• D. A, E, C, D, B

Hint:

Air passes from the mouth or nose to the pharynx, larynx, trachea, and finally into the lungs.

Answer 1

The Correct Option is C

Concept: The respiratory system allows the intake and exchange of gases in the body. During breathing, air follows a specific pathway through different respiratory organs before reaching the lungs. The normal passage of air is: \[ \text{Oral cavity} \rightarrow \text{Pharynx} \rightarrow \text{Larynx} \rightarrow \text{Trachea} \rightarrow \text{Lungs} \]

Step 1: Identify the entry point of air.
Air first enters through the: \[ \text{Oral cavity} \]

Step 2: Follow the respiratory pathway.
After entering the oral cavity, air passes through: \[ \text{Pharynx} \rightarrow \text{Larynx} \rightarrow \text{Trachea} \] and finally reaches the: \[ \text{Lungs} \]

Step 3: Determine the correct sequence.
Thus, the correct order is: \[ A, C, D, B, E \] Hence, the correct answer is: \[ \boxed{(C)\ A, C, D, B, E} \]
