Heart Valves

Heart valves are like checkpoints within the heart that control blood flow, ensuring it moves in the right direction. There are four main valves: the tricuspid, pulmonary, mitral, and aortic valves. They open to let blood pass through when the heart contracts and close to prevent backflow when it relaxes. This coordinated action helps maintain efficient circulation, delivering oxygen-rich blood to the body and oxygen-poor blood to the lungs for oxygenation. Proper valve function is essential for overall heart health, and issues with these valves can lead to conditions like regurgitation or stenosis, affecting the heart's ability to pump effectively.
