The pulmonary valve (PA) is a valve in the heart that regulates blood flow from the left ventricle to the lungs. The PA valve prevents backflow of blood into the left ventricle and reduces the volume of blood that returns from the lungs back to the left atrium.
The pulmonary valve has a special shape that helps it open blood towards the right ventricle and close it when flow reverses. It consists of three main parts: the valve, the valve part and the chords. Each valve has two narrowed parts: crescendo and decrescendo. The flap part is smooth on one side, and has grooves and grooves on the other, which allows the flaps to fit tightly against each other, creating an airtight seal when it closes. The chords, which are attached inside the leaf channels, help them move freely and prevent them from getting stuck.
The functions of the pulmonary valve in the body are extremely important. The pulmonary veins, which carry oxygenated blood from the lungs to the right atrium, collect in veins in front of the pulmonary valve, which gives rise to the pulmonary artery. This artery transports blood to the lungs and back to the entire circulatory system. If the pulmonary valve is open, then
