ANATOMY

Detailed explanation-1: -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-2: -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-3: -The oxygen-rich blood returns to your heart through the pulmonary veins. Visit our How the Lungs Work page to learn more about what happens to the blood in the lungs. The oxygen-rich blood from the lungs then enters the left atrium and is pumped to the left ventricle.

Detailed explanation-4: -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-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
