veins take the CO2 back to the lungs as a waste.
The pulmonary veins carry blood from the lungs back to the heart.
Veins carry stale, or deoxygenated blood from the body back to the heart. The exception to this rule is the pulmonary veins, which carry oxygenated blood from the lungs to the heart.
The pulmonary veins are veins which carry oxygenated blood (unlike most veins) back from the lungs to the left atrium of the heart.
The pulmonary veins are the only veins that carry oxygenated blood. They transport blood from the lungs back to the heart for distribution to the rest of the body.
The pulmonary arteries carry blood from the heart to the lungs and pulmonary veins carry blood back to the heart.
Veins primarily carry deoxygenated blood back to the heart, with the exception of the pulmonary veins, which transport oxygenated blood from the lungs. The blood in veins also contains waste products, such as carbon dioxide and metabolic byproducts, which are to be expelled from the body. Additionally, veins can carry small amounts of nutrients and hormones, although these are more commonly transported by arteries.
Aorta carry that. And the veins carry the oxygen poor blood back to the heart and lungs.
The arteries carry highly oxygenated blood. The veins carry deoxgenated blood and cellular wastes back to the kidneys to process waste and to the lungs to exchange CO2 for more O2.
Arteries carry oxygenated blood from the lungs around the body. Veins carry 'used' blood back to the lungs.
The pulmonary veins are found in pairs. Two from each lung. They carry oxygenated blood from the lungs to the heart.
They are called the Pulmonary Veins. They are the only types of veins that carry Oxygen-Rich blood (usually Arteries do that). These Pulmonary Veins carry blood that has been re-oxygenated in the lungs back to the heart for distribution to the body through the Aorta/Descending Aorta. Hope this helped!
Arteries carry oxygenated blood to the body tissues and organs. Veins carry deoxygenated blood from the tissues back to the heart and lungs where it becomes oxygenated again.
