Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Surfactant keeps the alveoli from collapsing.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -It is established that pulmonary surfactant reduces surface tension at the air–water interface in the alveoli, thereby preventing collapse of these structures at end-expiration. In this manner, surfactant reduces the work associated with breathing.

Detailed explanation-2: -Pulmonary surfactant is essential for life as it lines the alveoli to lower surface tension, thereby preventing atelectasis during breathing.

Detailed explanation-3: -There is no known way to prevent a collapsed lung. Following standard procedure can reduce the risk of a pneumothorax when scuba diving. You can decrease your risk by not smoking.
