There are three cusps in the aortic valve; the right, left and noncoronary cusps The aortic semilunar valve is composed of three cusps and opens only when the left ventricle contracts. I hope this helps
Between the Atria and Ventricles of the heart are the aptly named Atrioventricular valves. The valve between the right atrium and ventricle is called the Tricuspid because id has three Cusps (of small flaps the are pushed together and closed when under pressure). The valve between the left atrium and ventricle is called the Bicuspid because it has two cusps, of more often called the Mitral Valve because its two cusps look like a bishops hat.
Mitral valve lies between left atrium and left ventricle. It has got two cusps. So it is also called as bicuspid valve. It allows flow of blood from left atrium to left ventricle. The blood flow in reverse direction is prevented by the valve.
Mitral Valve
one has three cusps (tri) and the other has two (bi)
The valve between the right auricle (or atrium) and right ventricle is the tricuspid. The one between the left auricle and ventricle is the mitral. There is no valve between the left auricle and right ventricle.
Tricuspid valve (located between the Rigth Atrium and Right Ventricle in the heart) is also known as the Right Atrioventricular valve. The name "Tricuspid" indicates its structure, or form, as it has three flaps (or cusps), against the Bicuspid Valve (located between the Left Atrium and the Left Ventricle), which only has two. For more info see the related links.
The LEFT ventricle and pulmonary artery are not connected by a valve. The RIGHT ventricle is connected by the pulmonic valve. The mitral valve separates the left atrium from the left ventricle and the tricuspid valve seperates the right atrium from the right ventricle.
right atrium - right ventricle = TRICUSPID VALVE; right ventricle - lungs = PULMONARY SEMILUNAR VALVE; lungs - left atrium = not really a valve, more a perforation in the left pericardium; left atrium - left ventricle = MITRAL VALVE; left ventricle - aorta = AORTIC SEMILUNAR VALVE.
The left atrioventricular (AV valve) is also called the Mitral valve.
Bicuspid valve (also called mitral valve) is located between the left auricle (atria) and left ventricle of heart.
