Closed tricuspid and mitral valvesWhen the right ventricle is full, the tricuspid valve closes and keeps blood from flowing backward into the right atrium when the ventricle contracts (squeezes).When the left ventricle is full, the mitral valve closes and keeps blood from flowing backward into the left atrium when the ventricle contracts. The steps below show how the blood flows through the heart and describes how each valve works to keep blood moving. There are four chambers that make up the heart – two on the left side and two on the right. The physical heart is composed of four chambers. The ventricles are the two lower chambers that pump blood into the arteries. When this happens the effects are decreased heart rate; reduced preload through vasodilation and increased urinary output;stimulation of the Vagus nerve; and inhibited ventricular hypertrophy. Chambers of the heart Chambers of the heart The heart has four chambers: two atria and two ventricles. The chambers of the heart provide a multiple step pathway for blood to be first sent to the lungs for respiration and then dispensed to the body's cells to keep us alive.

The two larger lower chambers are the ventricles. The main pulmonary artery extends from the right ventricle and branches into left and right pulmonary arteries, which extend to the lungs. The valves prevent the backward flow of blood. The right and left atria also perform an endocrine function with the release of atrial natriuretic peptide (ANP), blunting the effects of epinephrine, endothelin and the renin-angiotension-aldosterone cascade.
