33.
Fluid will not flow in a tube unless there is unequal pressure.
34.
Blood flows due to a pressure gradient.
35.
Pressure is created by arterial stretch during systole which exerts a force on the blood within
during diastole.
36.
Diastolic pressure is created by arterial elastic recoil which exerts a force on the blood within.
37.
Diastolic pressure is created by ventricular vacuum.
