29 results about "Oxygen diffusion" patented technology

From the alveoli, the oxygen from the air you breathe enters your blood in nearby blood vessels. This is a process called oxygen diffusion. Once your blood is oxygenated, it carries oxygen throughout your body. Another form of diffusion occurs when blood containing carbon dioxide travels back to your lungs.
