The pressure in the large systemic veins leading into the heart is called what?
a) preload
b) afterload
c) systemic venous pressure
d) central venous pressure
e) peripheral venous pressure
Answer
The correct answer is Central Venous pressure.
The blood pressure in the vena cava near the right atrium is known as the central venous pressure. The central venous pressure is due to the returing of the blood to the heart and its pumping back to the arterial system. It is the direct measurement of blood pressure in the vena cava and right atrium. It can be measured by using a mkanometer or transducer.
