ANATOMY

Detailed explanation-1: -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-2: -There are 4 total pulmonary veins-with 2 pulmonary veins coming from each lung, left and right-that empty into the left atrium of the heart. Two pulmonary veins emerge from the hilus of each lung, and each pulmonary vein receives blood from 3-4 bronchial veins apiece before draining into the left atrium.

Detailed explanation-3: -Lungs: In your lungs, your blood refills its oxygen supply and gets rid of carbon dioxide. 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-4: -The pulmonary veins are blood vessels that carry oxygenated blood from the lungs and drain into the left atrium of the heart. There is a total of four pulmonary veins; two from each lung. Pulmonary veins are the only veins in the body that carry oxygenated blood.

Detailed explanation-5: -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.
