The two atrioventricular valves are mitral valve and tricuspid valve while the two semilunar valves are aortic valve and the pulmonary valve.
You must mean the four chambers of the heart. The upper two are caller the left and right atria and the lower two are the left and right ventricles.
If your valves are not working then your blood will flow in the wrong direction
There are four valves in the heart--the aortic valve, pulmonary valve, mitral valve, and tricuspid valve--each at the exit of one of the heart's four chambers.
As in all mammals, horses have four valves in their hearts.
The Endocardium, the inner layer of the heart.

The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
3 this answer is incorrect there are 4 valves in the human heart.

valves keep blood from flowing back into the heart and help pump oxygen-poor blood back to the heart.
The four heart valves.
Overview. In heart valve disease, one or more of the valves in your heart doesn't work properly. Your heart has four valves that keep blood ...
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.
As in all mammals, horses have four valves in their hearts.
The part of the heart that opens when blood flows though is called the valve. There are four valves in the heart, two atrioventricular valves and two semilunar valves.

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).
