The heart is a tough operating mechanism which moves blood around the body through a very advanced system called arteries and capillaries; the blood is then carried back to the heart by means of veins. Blood pressure is the thrust of this blood in the body pushing up against the inside walls of the arteries as the heart is pumping.
This is a biology/anatomy video about Blood Pressure, its causes and effects. The pressure with which blood flows in the blood vessels is called Blood Pressure or BP. BP is measured using a special device called Sphygmomanometer.
