Explanation / Answer

57. In emphysema patients, the Expiratory Reserve Volume decreased due to the stretching of enlarged alveoli which lost the elasticity to recoil and fails to inhale or push out air.

58. Emphysema is a disease characterized by dilation of the alveolar spaces and destruction of the alveolar walls. With their loss, much of the elastic recoil of the lung is also lost.This results in a chronically overinflated lung leads to high total lung capacity, functional residual capacity, and residual volume. So residual volume increased in emphysema patients.

59. Unlike in emphysema, asthmatic patients have reduced tidal volume as the hyperinflation of the alveolar cells.

61. The Total Lung Capacity of a young adult male is 6 litre of air. In the given data , the TLC is 600ml. That indicate the patient is male.
