Right lung

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 blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs.
Detailed explanation-3: -From there, blood is pumped out through the aortic valve into the aortic arch and onward to the rest of the body. The left ventricle is the thickest of the heart’s chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
Detailed explanation-4: -Right ventricle: Receives blood from the right atrium; pumps blood into the pulmonary artery.
Detailed explanation-5: -Right ventricle (VEN-trih-kul): one of the four chambers of the heart. The right ventricle pumps blood low in oxygen to the lungs. In the lungs, the blood then gets a “refill” of oxygen.
