Tricuspid valve has three flaps and it is located between the right auricle and right ventricle. It prevents the blood from flowing back into the auricle.
The mitral or bicuspid valve is situated between left auricle and left ventricle. It has two flaps which help in maintaining the blood flow in one direction (from left auricle to left ventricle). Tricuspid and bicuspid valves are together called auriculo-ventriclar valves.
Semilunar valves has flap which resembles half moon. Pulmonary semilunar valve keep the direction of blood flow from right ventricle to lungs and aortic semilunar valve keep the direction of blood flow from left ventricle to aorta.

Four valves of the heart pump?
The two atrioventricular valves are mitral valve and tricuspid valve while the two semilunar valves are aortic valve and the pulmonary valve.
What are the names of the 2 semilunar valves?
The two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve.The two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve.
What are all the valves in a heart?
There are four valves of two types (atrioventricular valves and semilunar valves). The four valves are :Tricuspid Valve (between the right atrium and the right ventricle)Pulmonary Valve* (semilunar valve between the right ventricle and the pulmonary artery)Mitral Valve (between the left atrium and the left ventricle)Aortic Valve (semilunar valve between the left ventricle and the aorta)*sometimes called the Pulmonic ValveThis does not include the other two valves: the Thebesian valve, which can be sometimes absent in healthy individuals; and the eustachian valve, which is important during the fetal stages of life but is not necessary in adults.
Valve preventing backflow into ventricles?
there r two valves: aortic semilunar valve and pulmonary semilunar valve
How is a heart beat produced?
The heart beat, also called heart sounds, is produced by the closing of the valves. The valves produce two sounds, known as lub-dub. The atrioventricular valve closing produces the first sound, or lub, and the semilunar valve closing produces the second sound, or dub.
How many valves are in the blood circulatory?
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).
What part of the heart opens when blood is flowing through?
The valves of the heart open when blood is flowing through, allowing it to move from one chamber to another. The atrioventricular valves open to allow blood to flow from the atria to the ventricles, and the semilunar valves open to allow blood to flow out of the heart into the arteries.
Four valves of the heart pump?
The two atrioventricular valves are mitral valve and tricuspid valve while the two semilunar valves are aortic valve and the pulmonary valve.
What are two of the valves of atrioventricular?
The bicuspid valve.
What are the names of the 2 semilunar valves?
The two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve.The two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve.
What two blood vessels contain semilunar valves?
Right at the very start of the aorta is the aortic valve and at the very start of the pulmonary artery is the pulmonart valve, each of which are semilunar. In the heart there are two semilunar valves that lad to blood vessels. The pulmonary semilunar valve leads to the pulmonary trunk, and the Aortic semilunar valve leads to the Aorta.
What are all the valves in a heart?

The four valves are :Tricuspid Valve (between the right atrium and the right ventricle)Pulmonary Valve* (semilunar valve between the right ventricle and the pulmonary artery)Mitral Valve (between the left atrium and the left ventricle)Aortic Valve (semilunar valve between the left ventricle and the aorta)*sometimes called the Pulmonic ValveThis does not include the other two valves: the Thebesian valve, which can be sometimes absent in healthy individuals; and the eustachian valve, which is important during the fetal stages of life but is not necessary in adults.
Valve preventing backflow into ventricles?
there r two valves: aortic semilunar valve and pulmonary semilunar valve
What structures in the heart prevent the back flow of blood?
The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
How is a heart beat produced?
The heart beat, also called heart sounds, is produced by the closing of the valves. The valves produce two sounds, known as lub-dub. The atrioventricular valve closing produces the first sound, or lub, and the semilunar valve closing produces the second sound, or dub.
Semilunar valve are found at the beginning of what two vessels?
There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
The second heart sound is caused by?
Closure of the two atrioventricular valves, specifically the tricuspid and mitral valves.
