1. right atrium 2. right ventricle 3. left atrium 4. left ventricle These listed above are the four chambers of the heart. In between each chamber and the ventricles and large vessels leaving the heart, there are valves that allow the flow of blood in one direction but upon closing do not allow back flow (if they are working correctly). Between the right atrium leading into the right ventricle is an atrioventricular valve called the Tricuspidvalve. It is named for the three flaps from which it is made. Between the right ventricle and the pulmonary veins is a semilunar valve called the Pulmonary valve. Coming in between the left atrium and the left ventricle is an atrioventricular valve known as the Mitral valve (the shape is similar to the mitres worn by bishops) then in between the left ventricle and the aorta is a semilunar valve called the Aortic valve.
SIMPLE ANSWER: The four valves of the heart can be grouped into two pairs. There is the Mitral Valve and Tricuspid Valve which control the blood flow from the atria to the ventricles, and there is the Aortic Valve and the Pulmonary Valve which control blood flow out of the ventricles.

Coachleft atrium- takes in blood that is high in co2 low in o2
right atrium- takes in blood high in o2 low in co2
left ventricle- sends blood to aorta
right ventricle- sends oxygenated blood to body
left atrium- takes in blood that is high in co2 low in o2
right atrium- takes in blood high in o2 low in co2
left ventricle- sends blood to aorta
right ventricle- sends oxygenated blood to body
O.o..... these are the chambers of the heart, but they aren't valves. Valves are the little things between the chambers of the heart and pulmonary artery and the aorta, to keep the back flow of blood from happening. The valves only go one way.
Atrioventricular valves
The tricuspid valve is the the one between the right atrium and ventricle.
The mitral valve (or bicuspid, as it is shaped that way) is between the left atrium and ventricle.
Semilunar valves
The pulmonary valve is between the right ventricle and pulmonary artery, leading to the lungs.
The aortic valve is between the left ventricle and the aorta, which leads to the rest of the body for systemic circulation.
These are both shaped like a semilunar, hence the name.
haha using hence is funny :p
The four valves in the heart are:
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.
* The tricuspid valve is between the right atrium and right ventricle. * The pulmonary or pulmonic valve is between the right ventricle and the pulmonary artery. * The mitral valve is between the left atrium and left ventricle. * The aortic valve is between the left ventricle and the aorta.

Where would you expect the blood to pass through valves?
There are a set of 4 valves in the heart in a part of the heart called the "skeleton". These are the Mitral (a bicuspid), Tricuspid, Aorta, and the Semiliunar valves. There are valves in the veins which prevent back flow.
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
What are the names for the two different sets of heart valves?
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.
Where can valves be found other than the heart?
Valves can be found in the heart aswell as the veins
List the valves of the heart and describe how they operate.?
DESCRIBE THE ACTION OF HEART VALVES. WHEN DO THEY OPEN AND CLOSE?
