large intestine 3d model

Ultra-realistic 3D anatomical model of the large intestine, including the cecum, ascending, transverse, descending, sigmoid colon, and rectum, shown in accurate human orientation. Surrounding the intestine, depict the main vascular trunks with anatomical precision: Arteries (in red): Superior mesenteric artery (SMA) branching into ileocolic, right colic, and middle colic arteries, supplying the right and transverse colon. Inferior mesenteric artery (IMA) branching into left colic, sigmoid arteries, and the superior rectal artery, supplying the descending and sigmoid colon. Show the marginal artery of Drummond connecting both systems along the inner border of the colon. Veins (in blue): Superior mesenteric vein (SMV) and inferior mesenteric vein (IMV) draining into the portal vein, visualized posterior to the pancreas. Subtle labeling of portal confluence (SMV + splenic vein). Use semi-transparent colon walls to show the vessels in three dimensions, with lymph nodes as small pale-green spheres along th
