Drawing of colon seen from front
(ascending colon coloured blue)
|Right colic artery|
|Right colic vein|
|Celiac ganglia, vagus|
The ascending colon is smaller in caliber than the cecum from where it starts. It passes upward, opposite the colic valve, to the under surface of the right lobe of the liver, on the right of the gall-bladder, where it is lodged in a shallow depression, the colic impression; here it bends abruptly forward and to the left, forming the right colic flexure (hepatic) where it becomes the transverse colon.
It is retained in contact with the posterior wall of the abdomen by the peritoneum, which covers its anterior surface and sides, its posterior surface being connected by loose areolar tissue with the iliacus, quadratus lumborum, aponeurotic origin of transversus abdominis, and with the front of the lower and lateral part of the right kidney.
It is in relation, in front, with the convolutions of the ileum and the abdominal walls.
