editor note |
in mammals, villi are (largely?) absent from the large intestine, so we treat this as equivalent to small intestinal villus. small/large subdivision may not make sense for all species for which this is present (see ZFA). Note that VHOG quotes ISBN:978-0030223693 as suggesting there are some villi in the large intestine |

The entire digestive tract is lined by well developed villi, which are longest in the intestinal bulb and decrease progressively in size towards the caudal end of the intestine. No crypts are present, but, the regions between the villi, the intervillus pockets, have a crypt-like function. Cells are produced in the intervillus pockets and shed from the villus tips. Crosnier et al. 2005[TAO] |
