PATHOLOGY

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: -Adding oxygen to blood The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs.

Detailed explanation-3: -Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs. The pulmonary vein carries oxygen-rich blood from the lungs into the left atrium. Blood flows from the left atrium into the left ventricle through the open mitral valve.

Detailed explanation-4: -The pulmonary valve is located between the right ventricle and the pulmonary artery. Mitral valve.
