The heart has 4 chambers. The lower 2 are called ventricles and have thicker muscular walls than the upper 2 called the atria. The septum which divides the hearts two sides is made mostly of muscle.The atria receive blood from all parts of the body;the ventricles pump blood into circulation.
As well as having the 4 chambers it also has 4 valves to control blood flow. They have the same structure but differ in certain details.The 2 atrioventricular valves lie between the atria and ventricles. The mitral valve on the left side has 2 cusps (bicuspid) while the right side counterpart has 3 cusps (tricuspid). Two semilunar vales are the exits from the ventricles, the pulmonary valve between the right ventricle and pulmonary artery and the aortic valve between the left ventricle and the aorta.
