large surface area due to the presence of vili and micro-vili,
and constant blood flow through these vili maintain the concentration gradient.

Any time you're asked about diffusion always look at how surface area might be increased. It's an easy one. Thin walls also helps in the lungs and other places.

Whenever you have a question about diffusion, always think about Fick’s law. There are three major factors that influence the rate of diffusion across a membrane: surface area, concentration gradient and thickness of the surface.

Use YouTube with miss jercha a level biology. For each topic you will see structure *so* function links. Really helpful!
