Valve - Semilunar

: Unlike atrioventricular (AV) valves, semilunar valves do not have chordae tendineae (heart strings) or papillary muscles to hold them in place.

: Each valve typically consists of three thin, flexible leaflets (cusps) made of connective tissue and endocardium. semilunar valve

: Located between the right ventricle and the pulmonary artery . It directs deoxygenated blood toward the lungs for oxygenation. Structural Features : Unlike atrioventricular (AV) valves, semilunar valves do

There are two main semilunar valves, each positioned at a critical exit point of the heart: It directs deoxygenated blood toward the lungs for

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

: Located between the left ventricle and the aorta . It controls the flow of oxygen-rich blood to the rest of the body.
