If resistance in the blood vessels remains constant, the minute volume of blood is directly related to the difference between arterial and venous pressure.

Question

Quizplus · Accepted Answer

According to the formula for calculating minute volume of blood (minute volume = cardiac output), it is directly proportional to the difference between arterial and venous pressure if resistance remains constant. This is because the greater the pressure difference, the more blood will be pushed through the blood vessels, increasing cardiac output.

If Resistance in the Blood Vessels Remains Constant, the Minute
