Your answer is in the name of each valve actually. The left atrioventricular valve (AV) can also be called the bicuspid valve and the right atrioventricular valve can also be called the tricuspid vavle. If you think back to what you may have learned in Anatomy and Physiology 1, a word that has "uni" attached to the front of it usually means one or single, a word that has "bi" attached to the front of it usually means two or double, and a word that has "tri" attached to the front of it usually means three or triple.
So to answer your question, the left atrioventricular valve, which is also known as the bicuspid valve has two cusps and the right atrioventricular valve, which is also known as the tricuspid valve has three cusps.

What is the valve that is between the ventricles and their arteries?
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.
The tricuspid valve is located between which two chambers of the heart?
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.
How many cusps are there to the tricuspid valve?
There are 5 cuspids. If you want to know how many valves have cuspids, then the answer is two: One is a tricuspid and one is a bicuspid.
What are the mitral and tricuspid valves?
The heart has four chambers. Deoxygenated blood enters the right atrium from around the body via the superior and inferior vena cavae, and travels down through the tricuspid valve into the right ventricle.The right ventricle pumps the deoxygenated blood to the lungs to be oxygenated, via the pulmonary artery (the only artery that carries deoxygenated blood). It returns via the pulmonary vein (the only vein that carries oxygenated blood) into the left atrium.Oxygenated blood then enters the left ventricle (the heart's principle pumping chamber, and has particularly thick muscular walls) from the left atrium through the mitral valve. The left ventricle pumps the oxygenated blood at sufficient pressure to travel round the entire body, through the aortic valve and into the aorta.- Qu.mstr.
Where are the two valves in the heart?
There are actually four valves in the human heart. The heart has four chambers. The upper two are the right and left atria. The lower two are the right and left ventricles. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction. -The tricuspid valve is between the right atrium and right ventricle. -The pulmonary or pulmonic valve is between the right ventricle and the pulmonary artery. -The mitral valve is between the left atrium and left ventricle. -The aortic valve is between the left ventricle and the aorta. Each valve has a set of flaps (also called leaflets or cusps). When working properly, the heart valves open and close fully.
How many cusps does the aortic semilunar valve have?
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
What are the three aortic valve cusps called?
Left cusp Right cusp Posterior cusp
Why is the atrioventricular valve in the right ventricle called the tricuspid valve and the atrioventricular valve in the left called the bicuspid valve?
one has three cusps (tri) and the other has two (bi)
How many cusps does the valve between the left ventricle have?
78

How many cusps are there to the tricuspid valve?
There are 5 cuspids. If you want to know how many valves have cuspids, then the answer is two: One is a tricuspid and one is a bicuspid.
What is a synonym for 'tricuspid'?
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.
Why bicuspid valve has two cusps and tricuspid valve has tree cusps?
Still needs a valid answer. What's the purpose functionally of the 2 valves being differently shaped? I was proposed the same question by a student today, and the only answer I can come up with, besides because our common ancestors have it that way is there is a limitation of room in left ventricle. However what we think causes it is the fusion of the valves tissue from 3 cusps into 2 in human development.

What are the structures of the circulatory system that keep blood flowing in one direction?
Valves in your heart keep out the backwash of "dirty" blood, therefore it only travels from right to left to be "cleaned" and oxidized by the lungs. Once oxidized, it returns to the rest of the body and thus, back into the heart. Repeat!
What is the difference between the structure of the two sides of the heart?
Both sides of the heart have an atrium and a ventricle, however, the left side of the heart is thicker and stronger so it has a valve with only two cusps (bicuspid valve). The right side of the heart is not as strong and needs a valve with three cusps (tricuspid valve). Both valves are located between the atria and ventricles.
