Detailed explanation-1: -Hemodynamically, venous return (VR) to the heart from the venous vascular beds is determined by a pressure gradient (venous pressure, PV, minus right atrial pressure, PRA) divided by the venous vascular resistance (RV) between the two pressures as shown to the figure.
Detailed explanation-2: -Venous return is the volume of blood that returns from the veins to the atria each minute and is 5 l/min. Peripheral venous pressure is the pressure in the peripheral veins draining the body organs and tissues. It is the pressure differential between the peripheral and central veins that determines venous return.
Detailed explanation-3: -Answer and Explanation: The given statement is true. When the heart pumps the blood, pressure is generated against the boundaries of the blood vessels, and then blood is pushed from the heart. Blood pressure can be measured in two ways: diastolic and systolic blood pressure.
