What Is Pulmonary Heart Valve?


What is pulmonary heart valve?


The pulmonary heart valve, also known as pulmonic valve, is one of the four valves to regulate blood flow. It lies between the right ventricle and the pulmonary artery.

The pulmonary heart valve transports deoxygenated blood from the right ventricle to the lungs. When the right ventricle is filling with blood, the pulmonary heart valve is close and then opens the let deoxygenated blood pass through it. When all deoxygenated blood leaves the right ventricle, the pulmonary heart valve closes again.

The closure of the pulmonary heart valve produces the second heart sound (S2). The pressure in the right heart is low. Therefore, the right heart usually produces softer sound.
