|
opens to allow blood to the left ventricle, then closes to prevent blood from flowing back into left atrium
|
|
|
closes and keeps blood from flowing backward into right atrium when ventricle contracts
|
|
|
closes to prevent regurgitation of blood from the right ventricle back into right atrium
|
|
|
blood flows from right ventricle through pulmonary valve to pulmonary artery then into the lungs, where it picks up oxygen and deliver to your body
|
Detailed explanation-1: -Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs. While in the lungs, blood diverges into the numerous pulmonary capillaries where it releases carbon dioxide and is replenished with oxygen.
Detailed explanation-2: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
Detailed explanation-3: -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.
