ANATOMY

Detailed explanation-1: -The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

Detailed explanation-2: -Blood that needs oxygen flows from your body into the right atrium. It then flows through the tricuspid valve to the right ventricle. The right ventricle pumps the blood through the pulmonary valve and into your lungs, where it picks up oxygen. The oxygen-rich blood then flows to the left atrium.

Detailed explanation-3: -Blood first enters the heart’s right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.

Detailed explanation-4: -Tricuspid Valve. Has three leaflets or cusps. Pulmonary Valve (or Pulmonic Valve) (link opens in new window) Mitral Valve. Has two leaflets. Aortic Valve. Has three leaflets, unless it’s abnormal from birth, i.e., bicuspid aortic valve. 08-May-2020
