👉 The term "post-mesenteric" refers to a type of mesentery, which is a part of the digestive system that connects the small intestine and colon. This part of the digestive system plays a crucial role in absorbing nutrients from food into the bloodstream, as well as secreting digestive enzymes and hormones necessary for digestion. The post-mesenteric mesentery is typically located between the ileum (the small intestine) and the rectum (the large intestine).
