MP1725 Bowel - Portion of Ileum
This 3D printed specimen demonstrates a small loop of ileum and mesentery. A window into the mesentery has been dissected (removing fat and visceral peritoneum) to show arterial arcades in the mesentery (many short vasa rectae and more numerous arcades than in jejenum). There are several large lymph nodes surrounding the larger vessels near the root of the mesentery. A distinct feature of the fat in the mesentery extending up to (and indeed, beyond) the mesenteric border of the bowel. A small portion of the lumen has been opened to reveal the nature of the mucosal folding (fewer but larger folds than jejenum).
