Not at all. Each of the four main blood vessels that connect the heart to the circulatory system has a valve within in it. It's not uncommon to need more than one valve replacing.
In heart has a four valve the two valve is pump the up and the others valve pump the blood down. heart is pump the blood
Two
Mitral Valve
There are two Atrioventricular Valves in the heart. The first one, on the right side of the heart, is called the Tricuspid Valve (it has three 'flaps'). On the left side, the Atrioventricular Valve is called the Bicuspid or Mitral Valve (it has two 'flaps')
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.
The two atrioventricular valves are mitral valve and tricuspid valve while the two semilunar valves are aortic valve and the pulmonary valve.
Good And Bad
There are four valves of the heart: two are located between the atria and ventricles of the heart (called atrioventricular valves) and two are located in the major vessels leaving the valves (called semilunar valves). The left atrioventricular valve is also known as the bicuspid valve or the mitral valve. The right atrioventricular valve is also known as the tricuspid valve. The two semilunar valves are named after the vessel they lie within: the left semilunar valve is called the aortic valve because it lies within the aorta; the right semilunar valve is called the pulmonic valve because it lies within the pulmonary artery.Ruben JoubertThere are four valves in the human heart. There is the aortic vavle, the tricuspid valve, the pulmonary valve and the mitral valve.The are two types of four main valves. The first two are the atrioventricular valves. These valves separate the atria from the ventricles. The two atrioventricular valves are the mitril valve and the tricuspid valve. The other type of valve are the semilunar valves. The semilunar valves are between the ventricles (which pump blood) and the arteries that flow away from the heart. The two semilunar valves are the aortic and pulmonary valves.There are four one-way valves in a human heart. These are the only valves in the heart.There are four valves in the heart (not counting the valve of the coronary, the isotonic valve and the valve of the inferior vena cava): two atrioventricular valves (mitral valve and tricuspid valve); and two semilunar valves (aortic valve and pulmonic valve).
The name is the aortic valve. surgery.about.com/od/beforesurgery/qt/HeartValves.htm this is where i found it.
Left Atrium and Left Ventricle. Its right heart sided counterpart is the tricuspid valve.
The upper chambers of the heart are called auricles/atria and the lower chambers of the heart are called ventricles. The valve between the left atrium and the left ventricle is called the Bicuspid valve/Mitral valve. The valve between the right atrium and the right ventricle is called the Tricuspid valve.
The Tricuspid Valve (Right side) and the Bicuspid valve (left side) open to let blood flow to the heart.
