*Lymphatic nodules are present in the mucosa.
*Lymphatic nodules are present in the mucosa of the large intestine.
*Lymph nodes of the large intestine drain into one of two centres, the '''cranial mesenteric centre''' or the '''caudal mesenteric centre'''.
**The '''cranial mesenteric centre''' includes lymph nodes of the [[Small Intestine - Anatomy & Physiology|small intestine]] and the following lymph nodes of the large intestine:
**'''Caecal''' - drains the caecum.
**'''Colic''' - drains the ascending and transverse colon.
***The efferent vessels of these lymph nodes converge to form the cranial mesenteric trunk which drains into the chyle cistern.
**The '''caudal mesenteric centre''' includes the lymph nodes of the descending colon, which are situated in the mesocolon.
***The efferent vessels of these lymph nodes converge to form the caudal mesenteric trunk which unites with the cranial mesenteric trunk to open into the chyle cistern.
