MEDICAL PHYSIOLOGY

Detailed explanation-1: -Pulmonary valve: Allows blood to pass into the pulmonary arteries; prevents blood from flowing back into the right ventricle.

Detailed explanation-2: -Pulmonary Valve (or Pulmonic Valve) Separates the right ventricle from the pulmonary artery. 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 pulmonary valve prevents blood from going backward from the pulmonary artery to the right ventricle. Mitral valve: This valve has two leaflets. They allow blood to flow from the lungs into the left atrium.

Detailed explanation-4: -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. In the lungs, the blood receives oxygen then leaves through the pulmonary veins.

Detailed explanation-5: -Its main function is to help oxygen-poor blood reach your lungs, where it gains oxygen and gets rid of carbon dioxide. Your pulmonary valve has three leaflets that open and close to start and stop blood flow toward your lungs with each heartbeat.
