|
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: -The pulmonic valve is between the right ventricle and the pulmonary artery, which carries blood to the lungs. The aortic valve is between the left ventricle and the aorta, which carries blood to the body.
Detailed explanation-2: -The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.
Detailed explanation-3: -Pulmonary circulation is ordered from the right ventricle to the pulmonary arteries, through the lungs, to the pulmonary veins, and reenters the heart in the left atrium.
Detailed explanation-4: -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. It returns to the heart and enters the left atrium.
Detailed explanation-5: -Deoxygenated blood starts to run from the body. It flows into Superior/ Inferior Vena Cava. The flow of deoxygenated blood reaches the right atrium. The atrium will push the flow through the Tricuspid valve. The gore stays in the right ventricle. More items •30-Mar-2022
