Respuesta :
oxygen goes from your lungs into the red blood cells by simple diffusion
Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by simple diffusion.
It should be noted that oxygen diffuses from the lungs into the red blood cells. It then binds to hemoglobin. A molecule of hemoglobin can bind with four molecules of oxygen.
Since the red blood cells have cell membranes that are thin, this then enables oxygen to be able to diffuse quickly.
In conclusion, the correct option is simple diffusion.
