Blood pressure increases from the capillaries to the inferior vena cava.

Question

Quizplus · Accepted Answer

Blood pressure decreases as it travels from the capillaries to the inferior vena cava. This is because the capillaries have the smallest diameter and largest total cross-sectional area in the cardiovascular system, resulting in a decrease in blood pressure. The blood then flows through progressively larger veins, leading to a gradual decrease in resistance and increase in blood flow velocity, but a decrease in blood pressure. By the time the blood reaches the inferior vena cava, it has lower pressure than when it left the capillaries.
