Aortic Valve: Function, Location & Anatomy - Cleveland Clinic
Your aortic valve has three sections made of collagen. These sections are called leaflets, or cusps. In a healthy heart, the leaflets open wide to allow blood to flow through. Then, they come tightly together to prevent backflow. Some people are born with only two aortic valve leaflets.
