: Each valve typically consists of three thin, flexible leaflets (cusps) made of connective tissue and endocardium.
The are pocket-like structures in the heart that act as one-way gates between the ventricles and the major arteries. Named for their crescent-moon or "half-moon" shape, they ensure that blood flows forward into the body and lungs without leaking back into the heart. Types of Semilunar Valves semilunar valve

: Unlike atrioventricular (AV) valves, semilunar valves do not have chordae tendineae (heart strings) or papillary muscles to hold them in place. Types of Semilunar Valves There are two main
