The colon may seem like a simple and straightforward organ at first glance. In fact, its histology contains many nuances that must be taken into account when excluding inflammatory bowel disease. In this lecture, we will examine the structure of the colon in detail, beginning with the ileocecal valve and ending with the anus. We will also discuss the appendix, a kind of intestinal tonsil.
