Large Intestine, Black

Description

Posteriorly oriented through a semi-transparent trunk, the large intestine is highlighted from the cecum in the right iliac fossa up the ascending colon along the right lateral abdominal wall to the hepatic flexure, then across the transverse colon to the splenic flexure. The descending colon tracks inferiorly on the left, continuing into the sigmoid colon as it curves medially toward the pelvis, where the rectum lies in the midline. Surrounding soft tissues remain subdued so the haustrated contour and overall colonic frame read cleanly against the back-facing standing figure. Clear landmarks. A posterior presentation helps clarify how the colon relates to the posterior abdominal wall and why portions are relatively fixed, an anatomic distinction that matters during mobilization for colectomy and during interpretation of pain patterns from retroperitoneal segments. This view also supports teaching of colonic flexures and their proximity to the diaphragm and spleen or liver, a practical point when explaining referred pain or when considering risks during colonoscopy and polypectomy at angulated turns. The standing anatomical position reinforces common surface orientation used in clinic when discussing right-sided versus left-sided abdominal symptoms. Educators can drop this figure into gross anatomy or GI blocks to anchor the regional layout of the colon before moving to mesenteries, peritoneal reflections, and vascular supply. It also fits patient-facing materials on colorectal cancer screening, diverticular disease distribution, and postoperative expectations after segmental colectomy, while representing a Black adult female body habitus for more inclusive teaching sets.
