What veins carry rich blood?

Aorta Carries oxygenated blood from the heart around the body.

Do veins always carry deoxygenated blood?

Explanation: A common misconception is that veins always carry deoxygenated blood. Veins always return blood to the heart, but the pulmonary veins are bringing oxygenated blood back to the heart so that it may be pumped to the body’s tissues.

Why do we inject in veins and not arteries?

You always want to inject into a vein and never into an artery. Veins are blood vessels that carry blood from the extremities of the body back to the heart and lungs where it becomes re-oxygenated. Veins have no pulse, and the blood they carry is a deep, dark red because it is low in oxygen.

What is difference between veins and arteries?

Who purifies the impure blood?

Which artery does not carry blood?

What carries the materials all over the body?
