| | + | ==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. |
