Midgut starts with the 2nd half of duodenum a)comprises: - 2nf half of duodenum . duodenum is pretty constant in position in all species. Hangs of the mesodeum of the dorsal body wall. Ileum in human is 40 % of si. in horse only 10 to 12 inches. Hindgut starts 2/3 the way of the transverse colon. Mesocolon/descending mesocolon- provides ability to move arm around ruring rectal. Blood supply differentiates all of them: equine surface projections, caecum on right- human also right side. (bottom right) . in mammals, mostly on the right side. Horses- it is pressed up against right abdominal wall. So can put a needle in to let out gas: small intestine displaced to the left of caecum. Much busier on the left side of the body.
