The intestine can be divided into a small intestine and a slightly wider large intestine.[well established][VHOG] MA:0000337 MAT:0000047 MESH:A03.492.411.620 MIAA:0000047 OpenCyc:Mx4rvVjlIJwpEbGdrcN5Y29ycA Subdivision of digestive tract that connects the stomach to the large intestine and is where much of the digestion and absorption of food takes place (with the exception of ruminants). The mammalian small intestine is long and coiled and can be differentiated histologically into: duodenum, jejunem, ileum[WP,cjm,Kardong]. TAO:0001323 The terminal region of the mid intestine is comprised of specialized enterocytes that appear to play a role in mucosal immunity.
