Why the blood vessel that carrying oxygenated blood from lungs is a vein while the the other vessels carrying oxygenated blood are arteries?

It differs in pulmonary arteries and veins because they do the opposite thing to normal arteries and veins. Arteries usually carry oxygenated blood away from the heart to the body but pulmonary means lungs and the pulmonary artery carries de-oxygenated blood away from the heart but to the lungs and not round the body.
Veins usually carry de-oxygenated blood back to the heart but the pulmonary vein carries oxygenated blood to the heart which then pumps it into the aorta which takes it to the body. bla bla bla

Arteries are defined as carrying blood FROM the heart.
Thus the pulmonary artery carries blood depleted in oxygen to the lungs and the vein coming back to the heart form the lungs carries oxygenated blood as the oxygen has be supplied to it in the lungs.
This newly oxygenated blood is then pumped out of the heart again to go round the body (so most arteries carry oxygenated blood).

The strange vein is the "Hepatic Portal Vein" which starts in a capillary net in the intestines and terminates in a capillary net in the liver (ie does not come from or go to the heart at all).

What makes the pulmonary veins and arteries more confusing than other veins and arteries?
We usually think of arteries as the vessels that carry oxygenated blood to the body, and we usually think of veins as the vessels that carry spent blood back to the heart/lungs. But the vessels around the heart can be a little different. It is an artery that carries spent blood from the heart to the lungs (where they get re-charged with oxygen), and then it is a vein that carries this oxygenated blood back to the heart to then be pumped out to the body.To clear it up, realize that if a vessel is carrying blood out of the heart chambers, it is an artery. If the vessel is carrying blood back to the heart chambers, it is a vein. It is not oxygen content that defines a vessel as an artery or a vein.The coronary arteries are vessels that are carrying oxygenated blood out of the heart chambers and into the heart muscle itself; they are not carrying blood into the chambers for pumping. So they also are indeed arteries and not veins.
arteries are?
arteries are blood vessels that are part of the system carrying blood under pressure from the heart to the rest of the body-OR-Arteries are blood vessels that carry oxygenated blood out to the body/lungs. They are the largest form of vessel. In other words Arteries are blood vessels that carry rich blood away from the heart throughout the body. Arteries send rich blood away throughout the cells.
What are kind the blood vessel?
Arteries (carries oxygenated blood), veins (carries deoxygenated blood) and capillaries (blood vessels connecting arteries to veins and vice versa).
What vessel supplies the gut with oxygenated blood?
The vessel that supplies the gut with oxygenated blood is the MESENTERIC ARTERIES.
What is the difference between coronary arteries and vessels?
When people use the word vessel in relation to the cardiovascular system, they usually are referring to blood vessels like arteries, veins, or capillaries. Coronary arteries are specific blood vessels that carry oxygenated blood to the muscles (myocardium) of the heart.
A blood vessel that carries blood away from the heart is called?
There are two types of vessels carrying blood away from the heart. The one which carries oxygen rich blood from the heart to the rest of the body is called AORTA, while the vessels carrying oxygen poor blood from the heart to the lungs are called pulmonary veins.
What sends oxygenated blood from heart to body?
The circulatory system which includes the heart and arteries carry oxygenated blood to the body cells.
What blood vessel carries blood to the lungs?
The pulmonary arteries carry blood to the lungs to be oxygenated.
What vessel carries oxygenated blood to myocardium?
Coronary Arteries
Which vessel transports blood from the heart to the lungs?
The vessel that carries blood from the heart to the lungs is called the pulmonary vein. It is one of the few veins that carry oxygenated blood to the heart. The oxygenated blood enters the atrium of the heart.
Why are the pulmonary arteries and umbilical arteries called arteries instead of blood vessels?
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.
Why can an artery be defined as a blood vessel that transports oxygenated blood?
Yes, arteries are blood vessels that carry blood away from the heart.
