Introduction
Structure
- The caecum is a blind-ending diverticulum of the large intestine.
- It communicates with the ileum via the ileal orifice and with the colon via the caecocolic orifice.
- It consists of a base, body and apex, the apex being the blind-ending portion.
- It is attached to the ileum by a fold of peritoneum called the ileocaecal fold.

Species Differences
Canine
- On the right side of the abdomen.
- Unique because it has no direct connection to the ileum.
- Short and held in a spiral shape against the ileum by the ileocaecal fold.
Ruminant
- On the right side of the abdomen in the supraomental recess
- The apex points caudally.
- Relatively small and featureless: there are no taenia or haustra.
Horse
Pig
- On the left side of the abdomen, with the apex pointing caudoventrally.
- Cylindrical in shape.
- Three taenia are present
- The ventral taenia provides the attachment for the ileocaecal fold.
- The lateral and medial taenia are free.
