Question

All of the following are associated to the respiration of the elderly except:

a. decreased lung compliance
b. increased airway resistance
c. decreased vital capacity
d. increased alveolar macrophage activity
e. increased susceptibility to respiratory infection

Answer 1

The answer is D: Increased alveolar macrophage activity.

Step-by-step explanation:

The respiratory system of the elderly is a system that has lost a lot of elasticity (including the alveoli). The thoracic wall becomes stiff. There is a decrease in lung capacity (vital capacity). Decrease in blood concentration of O2. Reduction of alveolar macrophages, being susceptible to infectious processes.
