At high altitudes, when capillary pressure becomes too high,
A) fluid filters out of the blood and collects in the alveoli (pulmonary edema).
B) blood pressure decreases.
C) decreased breathing and heart rates.
D) blood pH increases to pathologic levels.

Question

Quizplus · Accepted Answer

At high altitudes, capillary pressure may increase due to decreased atmospheric pressure. This can cause fluid to leak out of the capillaries and collect in the alveoli, leading to pulmonary edema. Choices B and C are not directly related to capillary pressure at high altitudes, and D is not a known consequence of capillary pressure changes.
