produces protease, lipase and amylase which is then pushed into the small intestine

Question 8

what are the 3 functions of the villi?

Answer 8

There are many villi giving them a large surface area to transport the molecules into the bloodstream more quicker

They have a single layer of cells on their surface meaning that diffusion is a short distance

They have a good blood supply maintaining the concentration gradient

Question 9

what does the single layer of surface cells in the small intestine do?

Answer 9

makes the diffusion rate shorter

stores waste products while the remaining water is absorbed back into the body
then is transferred into the rectum
