We’ll occasionally send you account related and promo emails. A wave of electrical activity is firstly spread from the Sino-atrial node which spreads across both atria, this causes the atria to contract which forces blood down into the ventricles through the atrioventricular valves. This wave passes down the bundle of His to the Apex of the heart where the Ventricles contract upward, pumping blood out of the ventricles into the pulmonary artery and aorta through the semilunar valves.

The atrioventricular septum prevents the wave crossing the ventricles. A cycle can be defined by a series of repeated steps that produce an end product which is the same as the start product. How to cite this page Choose cite format: How about receiving a customized one?
