NEET Zoology Gas Exchange MCQ Question
Which of the following combinations correctly describe the characteristics and functions of the diffusion membrane involved in gas exchange?
It is composed of three layers, has a thickness of less than a millimeter, and facilitates the diffusion of O2 and CO2.
The diffusion membrane consists only of the alveolar epithelium and operates independently of the capillaries.
It has a thickness greater than a millimeter, allowing for more efficient gas exchange, especially for O2.
The diffusion membrane includes the endothelial layer of capillaries, is very thin, and enhances CO2 transport due to its higher solubility.
Correct Answer
Detailed Explanation
The diffusion membrane is indeed made up of three major layers and has a total thickness of less than a millimeter, facilitating gas exchange for both O2 and CO2 as described in the context.
