What kinds of cells are disposed in the intestinal crypts?

Which enzyme is not secreted by crypts of Lieberkuhn?

While the chyme is present within the small intestine, glands within this structure begin to secrete different types of digestive enzymes called carbohydrases (amylase, proteases, and lipases or fat splitting enzymes). The glands responsible for these enzymatic secretions are called the crypts of Lieberkuhn.

What is the function and location of villi?

What is their location and function? Solution 5: Villi are small finger-like projections found inside the inner walls of the small intestine. They v increase the surface area for absorption of the digested food. Each villus has a network of thin and small blood vessels close to its surface.

How do villi absorb nutrients?
