Answer to Question 1

ANS: B
Deflation of the lung does not follow the inflation curve exactly. During deflation, lung volume at any given pressure is slightly greater than it is during inflation. This difference between the inflation and deflation curves is called hysteresis.

Answer to Question 2

ANS: D
Elastic forces involve the tissues of the lungs and thorax, along with surface tension in the alveo-li. Frictional forces include resistance caused by gas flow and tissue movement during breathing.
