The heart to a fault contains valves on either side, it contains an Aortic valve that lettuce the backflow of squanderer from the aorta into the ventricles, the angular valve which has two cusps, this also stops backflow of blood from the ventricle to the atria, as the left ventricle contracts the bicuspidate valve stops blood going backwards, Tricuspid valve, has triad cusps and this also stops the backflow of blood to the atria when the right ventricle contracts, and eventually the Pulmonary valve which stops blood back menses through the ventricle from the pneumonic artery. Deoxygenated blood enters the right atria from the shining and substandard vena cavae. The right atrium then fills with blood, the blood passes through a one-way valve that takes the...
