Heart is a pumping organ in the body that pumps oxygen rich blood throughout the body and sends the impure or venous blood to the lungs where it is oxygenated so that it can be used by the body for various functions.
Heart has four compartments, also referred to as chambers. Two upper compartments are known as Atria and lower two are called ventricles. Right side of the heart, comprising of right atrium and right ventricle, is separated from the left side of the heart by partition (septum). Right atrium is separated from left atrium by tissue called Interatrial septum. Likewise, right ventricle is separated from left ventricle by Interventricular septum. This way, impure blood on the right side of the heart remains separated from oxygenated or pure blood on the left side of the heart.
Atria are connected to their respective ventricles through atrioventricular valves that ensure one way controlled blood flow from atria to the ventricles. They are Tricuspid valve and Mitral valve on the right and left side respectively.
Tricuspid valve consists of three flaps or cusps that open and close to function. Mitral valve is also known as bicuspid valve as it contains only two flaps or cusps.
Besides the above two valves, there are two more valves namely Pulmonary valve and Aortic valve. Pulmonary valve is situated between the right ventricle and pulmonary trunk and ensures one way blood flow out of the ventricle to be transported to the lungs for oxygenation. Aortic valve is situated between left ventricle and the largest artery or blood vessel in the body, named Aorta. It ensures one way blood flow from the ventricle into the Aorta to supply oxygen rich blood to the whole body.
Heart has 4 valves. A valve when healthy, its leaflets or cusps (flaps of tissue) open wide to enable unrestricted normal flow of the blood in one direction. During contraction of the ventricles, the cusps or the flaps close completely so as to prevent back flow of the blood.
Valves once diseased or damaged can be dysfunctional in the following two ways:
It puts stress on the heart and the function of the heart is compromised. Under such conditions the diseased or damaged valve needs to be repaired or replaced. Valve may be repaired, which means it is reshaped or trimmed to make it function properly or replaced. Replacement of the valve means that the diseased or damaged valve is removed altogether and a new valve is put in its place.
