Answer 1

Hey mate!!

when there is high pressure then force is exerted due to pressure which makes the bood flow .as the blood is inclosed in blood vessels so it has also some kind of potential energy which makes it flow


Hope it helps u ❤

Answer 2

Our circulatory system consists of a muscular pumping organ heart a network of vessels and fluid blood heart has to artery and to ventricles cardiac musculature is of excitable sinoatrial node generates the maximum number of action potential per minute and therefore it set the pace of activities of heart hence it is called the pacemaker
The action potential causes the atria and then the ventricles to undergo contraction followed by the relaxation the system forces the blood to move from the earth right ventricles and to the Pulmonary artery and the Aorta the cardiac cycle is formed by sequential events in the heart which is cyclic leech repeated and is called as cardiac cycle, and then blood move from auricle to ventricle.
