5. What is the PRIMARY (main) reason that blood continues to flow through the circulatory system during diastole?

a. The one-way valves of the veins prevent backflow.

b. Elastic energy stored in the large artery walls maintains a hydrostatic pressure gradient.

c. An increase in arteriole diameter enhances flow to the systemic tissues.

d. The skeletal muscle pump pushes blood through the entire circulatory system.

Answer #1

Large arteries like aorta are elastic artery. They have the property of elasticity i.e., during systole their wall stretched and during diastole because of the elastic recoil property,the wall come back to its normal position and it push the blood forward and hydrostatic gradient for blood flow is maintained.

So,the Answer is Option B.

Do give a thumbs up. Thank you.

    Blood Vessels and the Circulatory System Overview of Circulatory System Blood vessels form closed tubular systems which carry blood from the heart through the systemic and pulmonary systems. Arteries carry blood away from the heart to smaller arterioles, which feed capillary beds. The capillary beds empty into venules, which coalesce into larger veins. All veins eventually empty into the superior and inferior venae cavae or into the pulmonary veins. These vessels return blood to the heart. A. List the heart...

    In hemodynamics, blood flow through the cardiovascular system can be modeled as an electric circuit in which the blood serves as electricity, the blood vessels as resistive wires, and the heart as a battery (see Figure 1). Figure 1 Cardiovascular circuit model Ohm’s law states that the voltage drop ΔV across each element, the current I flowing through it, and its electrical resistance R are related by ΔV = IR. In a blood vessel, pressure difference between one vessel and...
