The pulmonary artery and pulmonary vein originates in the heart. What is different about them is that the pulmonary artery carries deoxygenated blood (blood without oxygen) as supposed to other arteries, which carry oxygenated blood. And the pulmonary vein carries oxygenated blood unlike other veins, which carry deoxygenated blood.
In the human body arteries carry oxygenated blood and veins carry deoxygenated blood. The pulmonary arteries and veins are exceptions to this rule. The pulmonary arteries carry deoxygenated blood, and the pulmonary veins carry oxygenated blood.
The Pulmonary Artery
Pulmonary artery/Systemic veins PCO2 = 45 PO2 = 40 Pulmonary vein/Systemic arteries PCO2 = 40 PO2 = 100
The Pulmonary arteries
yes
they carrythe blood to and from thelungs
pulmonary arteriovenous fistula
Pulmonary arteries and pulmonary veins are two different items. The pulmonary artery takes deoxygenated blood from the heart and into the lungs so that the blood can be oxygenated. The oxygenated blood then returns to the heart, via the pulmonary veins, in order to be pumped into the system circulation.
The pulmonary arteries carry blood to the lungs to be oxygenated.
Arteries and pulmonary veins
No. Pulmonary veins take blood from the lungs to the right atrium.(veINs take blood IN to the heart.) Pulmonary arteries take blood from the heart(left ventricle) to the lungs. But pulmonary veins are the only veins in the body to carry oygenated blood, and pulmonary arteries are the only arteries to carry deoxygenated blood.
The left pulmonary vein carries oxygenated blood from the left lung to the left atrium of the heart. The pulmonary arteries and veins are the only ones which are "opposite" as the rest of the bodies veins and arteries. Veins normally carry unoxygenated blood from the body back to the heart/lungs. Arteries normally carry oxygenated blood to the body from the heart. Pulmonary arteries carry unoxygenated blood from the heart to the lungs and pulmonary veins carry oxygenated blood from the lungs back to the heart.
The pulmonary arteries leave the right ventricle to travel to the heart, so carry deunoxygenated blood. The name "arteries" is used because the vessels are leaving the heart.The pulmonary veins, conversely, are coming back into the heart, so are veins, but they are carrying oxygenated blood.
