Vein
Artery - always carries blood FROM the heart Vein - always carries blood TO the heart The vein which brings blood to the heart from the lungs is the PULMONARY VEIN ('pulmonary' = lungs). The one carrying blood away from the heart to the lungs is the pulmonary artery. Easy.
a vein
Blood flow from a vein is slower than that from an artery.
An artery carries oxygenated blood. A vein carries DEoxygenated blood.
It is the pulmonary artery
Yes, it can, when you pop a blood vessel. You can do this by pushing too hard on a vein or artery. Also, when you get a cut it is coming out of a vein or artery.
it is a vein
During medical procedures, blood is typically drawn from a vein rather than an artery.
The Pulmonary artery carries blood from the heart to the lungs and the pulmonary vein carries blood from the lungs to the heart. Also this means the Pulmonary Artery is the only artery in the body which carries deoxygenated blood, and the Pulmonary Vein is the only vein in the body which carries oxygenated blood.
the smallest blood vessel is the capillary, then the vein, and the artery. (vein and artery depends though because when they diffuse they get smaller and close to the same size) but the smallest will always be the capillary.
Umbilical Vein, all other vessels have varying degrees of oxygenated and deoxygenated blood.
