Which factors are responsible for the decrease in the volume of the alveoli?
A) Compliance and lung recoil
B) Lung recoil and surface tension of water
C) Compliance and surface tension of water
D) Perfusion and lung recoil
Surface Tension
The elastic tendency of a fluid surface which makes it acquire the least surface area possible.
Lung Recoil
Decrease in the size of an expanded lung as a result of a decrease in the size (volume) of its alveoli; due to elastic recoil of elastic fibers surrounding alveoli and water surface tension of a thin film of water within alveoli.

Final Answer :
B
Explanation :
Lung recoil and surface tension of water are responsible for the decrease in the volume of the alveoli. Lung recoil is due to the elastic fibers in the lung tissue, and surface tension of water in the alveoli tends to collapse them, both contributing to a decrease in alveolar volume.
