Solution
This is an example of Simple Diffusion. In simple diffusion, substances move from an area of high concentration to an area of low concentration without the need for any transport proteins. This is a passive process, meaning it does not require any energy. In the case of oxygen moving from the lungs to the blood, it is moving from a high concentration (in the lungs) to a low concentration (in the blood), which is characteristic of simple diffusion.
