Answer 1

Hey there...

...=============

HEART_ HEART IS OPERATER OF BLOOD CIRCULATION

the pressure of blood circulation its depend on Action of heart

The rate of mean blood flow depends on both

blood pressure and the resistance to flow

presented by the blood vessels. Mean blood

pressure decreases as the circulating blood

moves away from the heart through arteries and capillaries due to viscous losses of

energy.

Mean blood pressure drops over the whole circulation, although most of the fall occurs

along the small arteries and arterioles.[ Gravity affects blood pressure via hydrostatic forces.

e.g., during standing), and valves in veins,

breathing, and pumping from contraction of skeletal muscles also influence blood pressure
in veins.
