This exchange process takes place in the aveolus (air sac) inside your lungs by diffusion.
it's from a different concentration gradient
the deoxygenated blood with carbon dioxide diffuse into a aveoli (which is in high concentration) and the aveoli release the oxygen into the blood stream (which is low concentration) therefore the blood will be oxygenated again
Arteries are blood carrying vessels which have thick, elastic, muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure.
All arteries carry oxygenated blood from the heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.

A 5% confidence interval was used in this test with percentages 31.8% for us and 11.9% for Hungarians.
