Detailed explanation-1: -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-2: -Pulmonary veins: Your pulmonary veins do the opposite job of your pulmonary arteries. They collect oxygen-rich blood and carry it from your lungs to your heart. This blood empties into your heart’s top left chamber (left atrium).
Detailed explanation-3: -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-4: -Pulmonary vein brings blood to left atrium from lungs.
