Which of the following statements is true?
A) Pulmonary vascular resistance (PVR) is equal to systemic resistance.
B) Pulmonary vasculature is a high-pressure, high-resistance circulation.
C) Systemic vascular resistance (SVR) is less than PVR.
D) SVR is normally approximately 10 times higher than PVR.

Question

Quizplus · Accepted Answer

Systemic vascular resistance (SVR) is normally approximately 10 times higher than pulmonary vascular resistance (PVR). This is because the systemic circulation has a much greater vascular bed and a higher blood pressure than the pulmonary circulation. Pulmonary vasculature, on the other hand, is a low-pressure, low-resistance circulation that allows for efficient gas exchange in the lungs.
