- The small intestine needs a large surface area as it is adapted for absorbing nutrients from food that the body needs.
- The small intestine has villi, which increase the overall surface area, maximizing the area available for absorbing nutrients.
- The villi have very good blood supplies, as they each have a capillary in them, so when substances are diffused they go straight into the blood stream. Just like the alveoli in the lungs, the epithelium is only one cell thick meaning that there is less distance for the nutrients to diffuse across.
I think there might be more information about this on the BBC Bitesize website, but in the meantime I hope this helps
