It lies in the right iliac region, and from its medial and posterior part a worm-shaped outgrowth, the vermiform process, is prolonged (Fig. 951). 2. Colon Ascendens. — The ascending colon ascends vertically in the right lumbar region as far as the inferior surface of the liver: here the gut bends to the left, forming the flexura coli dextra ( hepatic flexure), and then passes trans- versely across the abdomen, towards the spleen, as the transverse colon. 3. Colon Transversum.—The transverse colon, a loop of intestine which passes across the abdominal cavity in an irregular looped manner. It ends at the inferior extremity of the spleen. There it turns downward, forming the flexura coli sinistra ( splenic flexure), and passes into the descending Haustra (Sacculations) Taenia coli Appendices epiploicae Fig. 950.—Large Intestine. A piece of transverse colon from a child two years old. The three chief characteristics of the large intestine- sacculations, taeniae, and appendices epiploicae—are shown. 4. Colon Descendens.—The descending colon runs down on the left side, from the splenic flexure to the rectum. It is usually divided into the following parts:— (a) Descending colon, which extends down to the crest of the ilium. (&) The iliac colon extends from the crest of the ilium to the superior aperture of the pelvis, where it is succeeded by the pelvic colon. (c) The pelvic colon is a large loop of intestine which is usually found in the pelvis. The iliac and pelvic portions of the colon taken together are sometimes described as the colon sigmoideum. 5. Intestinum Rectum.—The rectum, the terminal part of the large bowel, succeeds the pelvic colon, and ends in the anal canal, which opens on the surface at the anal orifice. In its course the large bowel
