==Introduction==
 +
Rabbits are monogastric hindgut fermenters that eat a herbivorous diet.
 +
 +
==[[Stomach - Anatomy & Physiology|Stomach]]==
 +
*Simple and large
 +
 +
==[[Small Intestine - Anatomy & Physiology|Small Intestine]]
 +
*Functions similar to other animals but there are anatomical differences.
 +
*The caudal flexure of the duodenum is long and coiled, and may be referred to as the transverse part of the duodenum.
 +
*The sacculus rotundus exists at the ileocaecal junction. It is an enlargement of the large intestine and contains lymphoid tissue.
 +
 +
==[[Large Intestine - Anatomy & Physiology|Large Intestine]]
 +
 +
===Caecum===
 +
*Large, about twice the length of the abdominal cavity. Folded into four parts that flex upon each other.
 +
*Thin-walled.
 +
*Visible on the external surface is a spiral constriction that runs 20-30 times around the caecum. This is related to the folding of the mucosa internally.
 +
*There is an appendix at it's distal end containing lymphoid tissue.
 +
 +
===Colon===
 +
*Has ascending, transverse and descending parts.
 +
*The '''ascending colon''' is very long and occupies most of the ventral abdomen.
 +
*First part has taenia and haustra, the second part does not and is arranged into coils that lie in the dorsal part of the abdominal cavity.
 +
*The '''transverse''' and '''descending''' colons have the same anatomical arrangement as in other species.
 +
 +
==Coprophagia==
 +
*Rabbits eat some of their faecal pellets, often produced in the early morning.
 +
*Pellets that are eaten differ to normal pellets as they are softer, covered in mucus and smaller.
 +
*The purpose of this may be to gain access to the vitamins produced by bacteria in the caecum.
