What are all the valves in a heart?

Answer 1

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 Valve

This 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.

Answer 2

There are four valves in the human heart: the atrioventricular (AV) tricuspid valve, the pulmonary semilunar valve, the AV bicuspid (or mitral) valve, and the aortic semilunar valve.

The AV tricuspid valve prevents deoxygenated blood in the right ventricle from flowing back into the right atrium.

The pulmonary semilunar valve prevents deoxygenated blood in the right and left pulmonary arteries from flowing back into the right ventricle.

The AV bicuspid valve prevents oxygenated blood in the left ventricle from flowing back into the left atrium.

The aortic semilunar valve prevents oxygenated blood in the aorta from flowing back into the left ventricle.

Answer 3

The two valves of the heart are: 1.The atrial valve 2.The ventral valve
