  • Hemoglobin Causes Net Diffusion of Oxygen (Interactive Demo) - Oxygen diffuses freely across oxygen-permeable membranes such as those found where capillaries (small blood vessels) in the lungs make contact with the air we breathe. When oxygen diffuses from the air in our lungs across the walls of these capillaries and into our blood, it is taken up by hemoglobin -- this causes even more oxygen to diffuse into the blood in order to balance the concentration (partial pressure) of free oxygen in our blood with that in the air in our lungs. Explore the interactive demonstration to see this diffusion in action.
