Question

In which part of the respiratory system does gaseous exchange take place?

• A. Alveoli
• B. Bronchioles
• C. Larynx
• D. Trachea

Hint:

Alveoli are the primary site for gas exchange in the lungs.

Answer 1

The Correct Option is A

Gaseous exchange in the respiratory system occurs in the alveoli, which are tiny air sacs in the lungs. Their thin walls and extensive capillary network facilitate the exchange of oxygen and carbon dioxide between air and blood.
- Bronchioles, larynx, and trachea serve as air passages but do not perform gas exchange.
