semilunar valves
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.
Arterial = aortic and carotid sinuses. There are also atrial, ventricular and pulmonary baroreceptors
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
Valves in your heart keep out the backwash of "dirty" blood, therefore it only travels from right to left to be "cleaned" and oxidized by the lungs. Once oxidized, it returns to the rest of the body and thus, back into the heart. Repeat!
The three phases of breathing are:The Active phase which is known as (inhalation/ inspiration).Phase 2. gas exchange in the lungs also known as (Internal exchange).The Passive phase which is known as (exhalation /expiration).

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 sounds LUB and DUB (also dup) are used to indicate a human heartbeat, with the LUB sound made by the closing of atrioventricular valves, and the DUB by the closing of the exterior or semilunar valves (aortic valves and pulmonary valve).
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).
The pulmonary valve(sometimes referred to as thepulmonic valve) is thesemilunar valveof the heart that lies between theright ventricleand thepulmonary arteryand has three cusps.Similar to theaortic valve, the pulmonary valve opens inventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.
Arterial = aortic and carotid sinuses. There are also atrial, ventricular and pulmonary baroreceptors
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
The most successful valvuloplasty results are achieved in treating narrowed pulmonary valves, although the treatment of mitral valve stenosis is also generally good. The aortic valve procedure is more difficult to perform and is generally less successful.
Semilunar valves include the aortic and pulmonary valves of the Heart. These valves do not have chordae tendineae, and are more similar to the valves in veins. Tricuspid vales are composed to three cusps which are attached with papillary muscles with the help of chordae tendineae.
There are four total valves in the heart. The Mitral and Tricuspid in the atria and ventricles The Aortic between the Aorta and left ventricle The Pulmonary between the Pulmonary artery and right ventricle
Pulmonary hypertension(P-h) is a syndrome that involves heart and lung. Diseases like COPD (chronic pulmonary disease) May also cause pulmonary hypertension. Not all the cardio-artery disease is related to P-h. Heart has valves. Dysfunction of these valves will cause tension to the blood flow, leading to p-h.
When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body. While the left ventricle is relaxing, the right ventricle also relaxes. This causes the pulmonary valve to close and the tricuspid valve to open.
