Detailed explanation-1: -Tricuspid valve: This valve has three leaflets. They allow blood to flow from the right atrium to the right ventricle. They also prevent blood from flowing backward from the right ventricle to the right atrium.
Detailed explanation-2: -Pulmonary Valve (or Pulmonic Valve) Opens to allow blood to be pumped from the right ventricle to the lungs (through the pulmonary artery) where it will receive oxygen. Prevents the back flow of blood from the pulmonary artery to the right ventricle.
Detailed explanation-3: -The tricuspid valve is made of three thin but strong flaps of tissue. They’re called leaflets or cusps. The leaflets are named by their positions: anterior, posterior and septal. They attach to the papillary muscles of the ventricle with thin, strong cords called chordae tendineae.
Detailed explanation-4: -The tricuspid valve regulates blood flow between the right atrium and the right ventricle. It prevents the backflow of blood to the right atrium when the right ventricle pumps blood to the lungs.
