*The ascending colon is very large and takes up most of the ventral abdomen.
*The ascending colon is very large and takes up most of the ventral abdomen.
***Continues caudally on the right. It is the shortest limb of the ascending colon.
***Continues caudally on the right. It is the shortest limb of the ascending colon.
*The '''transverse colon''' continues on from the right dorsal colon as the right dorsal colon turns medially.
*The '''transverse colon''' continues on from the right dorsal colon as the right dorsal colon turns medially.
*The right dorsal colon is attached by a mesentry to the dorsal abdominal wall, the base of the caecum, the root of the mesentry and the [[Pancreas - Anatomy & Physiology|pancreas]].
*The right dorsal colon is attached by a mesentry to the dorsal abdominal wall, the base of the [[Caecum - Anatomy & Physiology|caecum]], the root of the mesentry and the [[Pancreas - Anatomy & Physiology|pancreas]].
**This anatomical arrangement of mesentry allows the left ascending colon to twist and is a common cause of colic (colonic torsion).

*The ventral parts of the ascending colon are attached to the dorsal parts by a short mesocolon.
*The ventral parts of the ascending colon are attached to the dorsal parts by a short mesocolon.
*Passes from across the midline from right to left. It passes cranial to the root of the mesentry
*Passes from across the midline from right to left. It passes cranial to the root of the mesentry
*The transverse colon has '''two''' taenia.
*The transverse colon has '''two''' taenia.
*Turns caudally to become the descending colon at the level of the left kidney.
*Turns caudally to become the descending colon at the level of the [[Urinary System - Anatomy & Physiology|left kidney]].
