Why does cor pulmonale develop with chronic pulmonary disease?
A) The right ventricle pumps more blood than the left ventricle.
B) Pulmonary fibrosis and vasoconstriction increase vascular resistance.
C) Demands on the left ventricle are excessive.
D) Blood viscosity is increased, adding to cardiac workload.

Quizplus · Accepted Answer

Chronic pulmonary disease often leads to pulmonary fibrosis and vasoconstriction, which increase the resistance in the pulmonary arteries, causing the right ventricle to work harder and potentially leading to cor pulmonale.
