NEET · Biology · STD 11 - 14. Breathing and exchange in gases

Which of the following is not the function of conducting part of respiratory system ?

A Inhaled air is humidified
B Temperature of inhaled air is brought to body temperature
C Provides surface for diffusion of \(O _{2}\) and \(CO _{2}\)
D It clears inhaled air from foreign particles

Verified Solution

Answer & Solution

Correct Answer

(C) Provides surface for diffusion of \(O _{2}\) and \(CO _{2}\)

Step-by-step Solution

Detailed explanation

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
