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.

There 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).
6 total inferior vena cava, superior vena cava, four pulmonary veins, two on the left and two on the right.
There are 4 valves in the human heart

Valves in the circulatory system prevent blood from flowing into the wrong compartments. Valves also regulate the amount of blood that can be held in one compartment of the heart over a certain period.
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
The valves stop the blood flowing backwards through the circulatory system.
valves keep blood from flowing back into the heart and help pump oxygen-poor blood back to the heart.
To maintain the flow of blood in one direction
So blood doesn't flow backwards.
welll I guess so blood doesn't flow backwards.
if the valves failed then the blood would go in the wrong direction.
The heart and veins are the parts of the circulatory system that have valves to assist with blood flow.
Yes, but they have a closed circulatory system (their hearts have only two valves) and gills instead of lungs.
The circulatory system has a series of one-way valves built in which prevents blood flowing backwards.
In the human circulatory system: Valves prevent the backwards flow of blood. In a brass instrument: Valves are pushed to change the length of the pipe, thus changing the pitch.
