Why do some vein carry oxygenated blood while others carry deoxygnated blood?

By definition veins are any blood vessel that return to the heart, as arteries are any blood vessel transporting away from the heart. The Pulmonary Artery and Pulmonary Vein are unique in that virtually all veins carry deoxygenated blood and arteries carry oxygenated blood. These two exceptions however do the opposite. The blood being pumped out by the Left heart receives oxygen rich blood from the lungs only after the Right heart sends all blood returned to the heart through the Pulmonary Artery (carrying deoxygenated blood) to the lungs where the blood is oxygenated and then back to the Left heart through the Pulmonary Vein.

Which veins carry oxygenated blood?
They don't, arteries carry oxygenated blood
What type of blood does an artery carry?
oxygenated blood oxygenated blood oxygenated blood
Do arteries only carry oxygenated blood?
Arteries carry oxygenated blood away from the heart so it can travel to the various organs and be used. However the pulmonary artery is an exception as it carries deoxygenated blood to the lungs to gain oxygen. Otherwise the others only carry oxygenated blood :)
What carry's oxygenated blood?
Arteries carry oxygenated blood to the rest of the body from the aorta of the heart.
What veins carry oxygenated or blood red or blue?
Red veins carry oxygenated blood.
Do capillaries carry oxygenated or deoxygenated blood?
Capillaries carry Oxygenated (oxygen rich) blood and De-oxygenated (oxygen depleted) blood.
What veins carry oxygenated blood?
The only veins in an adult that carry oxygenated blood are the pulmonary veins, which carry blood from the lungs to the heart after it has been oxygenated. All other veins in the body carry relatively de-oxygenated blood.However in fetal circulation, the umbilical vein also carries oxygenated blood.Otherwise, arteries carry oxygenated blood to the body from the aorta and heart.
Do capillaries carry oxygenated blood?
Yes capillaries carry oxygenated blood :D
Does the pulmonary artery carry oxygenated blood or deoxygenated blood?
The pulmonary artery carries oxygenated blood. You can remember this easily because all ARTERIES carry oxygenated blood and all VIENS carry deoxygenated blood.
Do veins and ateries carry oxygenated blood?
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.
Is the blood in the Pulmonary artery oxygenatated or deoxygenated?
Blood in the arteries is oxygenated. Blood in the veins is de-oxygenated. With the exception of the pulmonary arteries which carry de-oxygenated blood, and the pulmonary veins that carry oxygenated blood.
What veins carry deoxygenated blood?
All veins carry de-oxygenated blood away from the heart except for the pulmonary vein and the umbilical vein, both of which carry blood towards the heart.
