Definition
The pulmonary valve is one of the four heart valves, located between the right ventricle and the pulmonary artery. It acts like a security guard 👮♀️ controlling the flow of blood to the lungs. The valve opens to allow deoxygenated blood to flow from the right ventricle into the pulmonary artery, which carries blood to the lungs. It prevents backflow, ensuring blood moves in the correct direction towards the lungs. The pulmonary valve is vital for pulmonary circulation, allowing blood to get oxygenated.
