heart valves and their functions
tricuspid valve
Prevents backflow into the right atrium when right ventricle contracts
pulmonary semilunar valve
Prevents backflow of blood into right ventricle when ventricles relax
atrioventricular (AV) valves
between atria and ventricles 1. left AV valve: bicuspid (mitral) valve 2. right AV valve: tricuspid valve
semilunar valves
between ventricle and artery 1. pulmonary semilunar valve 2. aortic semilunar valve
bicuspid valve
prevents backflow of blood into left atrium when left ventricle contracts
aortic semilunar valve
prevents backflow of blood into left ventricle when ventricles relax
