MICROANATOMY

Detailed explanation-1: -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-2: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

Detailed explanation-3: -The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Detailed explanation-4: -Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart.

Detailed explanation-5: -Pulmonary veins carry oxygenated blood from lungs to the left atrium of the heart. The anatomy of the pulmonary veins is variable with some anatomic variants. In clinical practice the difference between the normal anatomy of pulmonary veins with its variants and abnormal anatomy is very important for clinicians.
