Pulmonary circulation delivers oxygen to the blood and frees the blood of carbon dioxide.
It also, does
1- Gas exchange
2- Filtering emboli
3- Keep fluid out of alveoli
4- Metabolic function. e.g Removal of Bradykinin
to oxygenate the blood
Pulmonary circulation is part of the cardiovascular system . This is what carries blood from the heart.

The Pulmonary Valve prevents the back flow of blood, from the right ventricle to the pulmonary artery.
The pulmonary circulatory system carries oxygenated blood away from the lungs and deoxygenated to the lungs.
The functions of the valves are to direct the flow of blood in only one direction
To prevent blood from flowing back into the heart after contraction.
To bring blood from the heart to the lungs and back.
semilunar valves
arterial or semilunar valve
You have the atrioventricular valves that are the valves separating each atrium from the ventricles. The right AV valve is the tricuspid valve, while the left AV valve is the bicuspid/mitral valve. There are also two valves that lead from the heart to the pulmonary and aortic arteries. These are the pulmonary and aortic valves. They are both semilunar valves because of their shape.
There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
Due to pressure changes in different chambers of the heart. For example, when the atria contract, the bicuspid and tricuspid valves open. They get closed, when the ventricles contract. When the ventricles contract the aortic and pulmonary valves open. Aortic and pulmonary valves close, when the ventricles relax.
The two semiluar valves are at the exits from the ventricles the pulmonary valve between the right ventricle and the pulmonary artery and the aortic valve between the left ventricle and the aorta. This means that their function is to assist the heart valves to control blood flow.
semilunar valves
It is the pulmonary valve. Sigmoid is only a synonyme for semilunar (includes pulmonary and aortic valves).
arterial or semilunar valve
Valves allow forward blood flow. Valves prevent the back flow of the blood. You have beautiful small muscles in your ventricles. They are called as papillary muscles. They are attached to the bicuspid and tricuspid valves and simultaneously contract, during the contractions of the ventricles, to prevent the collapse of the cusps of the valves. The aortic and pulmonary valves prevent the back flow by there anatomical advantage.
Well, between the right ventricle and the pulmonary arteries is an atrioventricular valve called the PULMONARY VALVE . Between the left ventricle and the aorta is an atrioventricular valve called the AORTIC VALVE
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.
You have the atrioventricular valves that are the valves separating each atrium from the ventricles. The right AV valve is the tricuspid valve, while the left AV valve is the bicuspid/mitral valve.

There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
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.
Due to pressure changes in different chambers of the heart. For example, when the atria contract, the bicuspid and tricuspid valves open. They get closed, when the ventricles contract. When the ventricles contract the aortic and pulmonary valves open. Aortic and pulmonary valves close, when the ventricles relax.
