Question

In emphysema, which of these occur?

A) alveoli collapse
B) compliance increases
C) elevated PCO2 in the blood
D) depressed PO2 in the blood
E) All of the answers are correct.

Answer 1

In emphysema, alveoli collapse, compliance increases, elevated PCO2 in the blood, and depressed PO2 in the blood all occur.

Step-by-step explanation:

In emphysema, alveoli collapse, compliance increases, elevated PCO2 in the blood, and depressed PO2 in the blood all occur. Emphysema is a type of COPD that primarily arises from smoking tobacco. It causes destruction of the walls of the alveoli, reducing the surface area for gas exchange. This leads to a decrease in lung elastic recoil, increased air trapping in the lungs, and impaired gas exchange.
