An artery is a vessel that carries blood out of the heart, into the tissues. A vein is a vessel that carries blood from the tissues back to the heart. The fact that arteries carry oxygenated blood exclusively and veins, solely deoxygenated blood is not true. Our blood is oxygenated in the tissues of our lungs, so the vessels that bring this fresh, oxygenated blood from these tissues back to our heart are called... pulmonary veins! It's just a matter of vocabulary.
AnswerBlood coming from the pulmonary veins is oxygenated because it is coming from the lungs, the site of gas exchange.

and the pulmonary artery is blue because it carries deoxygenated blood.
It can be a little confusing when looking at anatomical models of the heart, but you just have to get over the mental definition of what color represents an artery vs. vein.
- Just remember that ALL veins carry (oxygen-poor) blood TO the heart.
- ALL arteries carry (oxygen-rich) blood AWAY from the heart

∙ 13y agoPulmonary veins and arteries are the exception to most: veins are generally deoxygenated, the pulmonary vein however carries oxygenated blood from the lungs so it is red. Likewise, the pulmonary artery is also opposite and carries deoxygenated blood to the lungs.

∙ 11y agoThe coloring of the models has to do with whether the blood is oxygenated or not, and the use of "artery" or "vein" has to do with whether the flow of blood in the blood vessel is going away from the heart (artery) or towards the heart (vein). So the pulmonary veins are red because the blood in them 1) has just been oxygenated by air in the lungs and 2) the direction of blood flow is towards the heart.

Wiki User
∙ 14y agoSince it is a vein, it is returning to the heart. 'Pulmonary' means it's coming from the lungs, so it will be oxygenated (red) blood.

Where is pulmonary veins located?
Pulmonary veins derive from the lungs. And reside in the cardiovascular system.
Do the pulmonary veins have valve?
Vena Cava has valves, if im not wrong, but pulmonary veins definitely do not have valves.
What vessels carry blood away from the lungs?
Pulmonary veins
Which characteristics describes the blood carried by the pulmonary veins?
The pulmonary veins are the only veins in the body that carry oxygenated blood. Like all veins the blood in the pulmonary veins travel toward the heart.
What is an pulmonary veins?
The pulmonary veins are veins which carry oxygenated blood (unlike most veins) back from the lungs to the left atrium of the heart.
What Veins in humans which ends in capillaries and not in larger veins?
Pulmonary veins
Where are the pulmonary veins located?
The pulmonary veins leave the lungs and carry blood to the left atrium of the heart.
Where does a red blood cell go after the systemic arteries?
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.
How may pulmonary veins in human body?
Veins are vessels that bring blood to the heart. Pulmonary veins carry oxygenated blood from the lungs to the left atrium. There are four pulmonary veins which extend from the left atrium to the lungs. They are the right superior, right inferior, left superior, and left inferior pulmonary veins.
Where do the pulmonary arteries and veins lie are they in the pulmonary circuit?
yes
Where does blood go after it leaves he pulmonary veins?
The Pulmonary arteries
Which chamber of the heart do pulmonary veins attach?
The pulmonary veins take oxygenated blood from the lungs to the left atrium.
