The four heart valves—tricuspid, pulmonary, mitral, and aortic—regulate blood flow through the heart and ensure it moves in the correct direction. The tricuspid valve controls blood flow from the right atrium to the right ventricle, while the pulmonary valve directs blood from the right ventricle to the lungs. The mitral valve allows blood to flow from the left atrium to the left ventricle, and the aortic valve regulates blood flow from the left ventricle into the aorta, supplying oxygenated blood to the body. Together, these valves maintain efficient circulation and prevent backflow.

How many Major valves in the human body?
The human body has four major valves in the heart: the mitral valve, tricuspid valve, aortic valve, and pulmonary valve. These valves regulate blood flow through the heart's chambers and into the major arteries. Additionally, the body has numerous other smaller valves, particularly in the veins, but the four heart valves are the primary ones referred to in this context.

They are similar in size, anatomy, and function. They both have four chambers and four valves, which is why it is sometimes used for a heart transplant
Do the four valves of the heart ensure one-way blood flow?
When they are working properly, the four valves of the heart ensure one-way blood flow. The atrioventricular valves prevent backflow into the atria, and the semilunar valves prevent backflow into the ventricles.
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).
