The fence of the Centre is formed from 3 layers: serosa, myocardium, and serosa.
The heart pumps blood with a rhythm determined by a bunch of footstep fashioning cells within the Storm Troops node.
These generate a current that causes muscle contraction of the centre, travelling through with the nerve muscle and on the physical phenomenon system of the centre. The concentrate receives stoc low in Oxygen from the circulation that enters the proper atrium from the superior and outclassed venae cave and passes to the proper heart ventricle. From present it's pumped into the circulation, through the lungs wherever it receives Oxygen and provides off nursery discharge. Vented blood then returns to the far left atrium of the heart, passes through the ventricle and is wired-up out through the artery to the ecumenical circulationwhere the O is employed and metabolized to greenhouse emission.
