Two types , 1. Atrio-ventricular valves a.Triccuspid valves: has 3 flaps guards the opening between right atrium and right ventricle b. Bicuspid valves (mitral valve): has 2 flaps guards the opening between the left atrium and left ventricle. 2. Semilunar valves: located between the ventricles and the big vessels a. Aortic valve : that pass blood from left ventricle to Aorta b. Pulmonary valve: which passes the blood from right ventricle to pulmonary trunk
