How is oxygen transported through the blood

How does oxygen from the lungs get transferred to the blood?

WebAs shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. WebOxygen enters the bloodstream through capillaries by diffusion, where oxygen transport takes place to the tissues via plasma and red blood cells (RBCs). Conversely, carbon dioxide diffuses out of the bloodstream and into the alveoli, expelled out from the body.
