The aortic valve is one of the four main valves in the heart, located between the left ventricle and the aorta. Its primary function is to regulate blood flow from the heart to the rest of the body, ensuring that oxygen-rich blood is efficiently delivered to vital organs and tissues. When the left ventricle contracts, the aortic valve opens to allow blood to flow into the aorta. Once the ventricle relaxes, the valve closes to prevent blood from flowing back into the heart. Proper functioning of the aortic valve is essential for maintaining healthy circulation and overall cardiovascular health.
