Thanks for the help :)
Intestine has villi and microvilli. Increase surface area to volume ratio - more absorbtion.
The capillaries help for the same reason, as there are lots of them there is a much larger surface area for absorbtion so everything can be absorbed much easier into the blood.
The thickness of villi/microvilli and capillaries also help as they are all only one cell thick.
Everything is just helping the absorption rate and efficiency :)
Okay thankyou :)
