ANATOMY

Detailed explanation-1: -Your pulmonary veins carry oxygen-rich blood. They travel in different directions. Your pulmonary arteries carry blood from your heart to your lungs. Your pulmonary veins carry blood from your lungs to your heart.

Detailed explanation-2: -The lung veins sometimes referred to as the pulmonary veins, are blood vessels that transfer freshly oxygenated blood from the lungs to the left atria of the heart.

Detailed explanation-3: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Detailed explanation-4: -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. Your lungs add oxygen to your blood.

Detailed explanation-5: -The main pulmonary artery and the subsequent right and left pulmonary arteries sit within the middle mediastinum. They arise from the right ventricle of the four-chambered heart and transport blood to the lungs.
