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: -The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it through the mitral valve to the left ventricle.
Detailed explanation-3: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
