WebThe pressure of the blood flow in the body is produced by the hydrostatic pressure of the fluid (blood) against the walls of the blood vessels. Fluid will move from areas of high to low hydrostatic pressures. In the arteries, the hydrostatic pressure near the heart is very high and blood flows to the arterioles where the rate of flow is slowed ... flutter twitter iconWebDue to the pressure change, blood is able to flow out through the semilunar valves and allows for the blood to leave.
