structure of the heart
The heart is divided into 4 chambers consisting of 2 atriums and 2 ventricles; the atria recives blood while the ventricles pump blood. the right atrium recieves blood from the vena cavas and coronary sinus; blood then moves to thr right ventricle where it is then pumped to the lungs. The lungs re-oxygenate the blood and send it to the left atrium. Blood moves from the left atrium to the left ventricle via the bicuspid valve; blood is pumped out of the left ventricle to the aorta, which sends blood to the organs and muscles of the body.
The heart is composed of three layers: the epicardium (outer layer), the myocardium (middle layer), and the endocardium (inner layer).
