Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.

The appendicular vein is the vein which drains blood from the vermiform appendix. It is located in the mesoappendix and accompanies the appendicular artery. The appendicular vein drains into the ileocolic vein
[1] [2] It descends behind the termination of the ileum and enters the mesoappendix of the vermiform appendix. It runs near the free margin of the mesoappendix and ends in branches which supply the appendix. Micrograph of entry point of appendicular arteries (arrows at level of inner muscular layer), not to be confused with a perforation.

The bands converge at the root of the vermiform appendix. At the rectosigmoid junction, the taeniae spread out and unite to form the longitudinal muscle layer. In the caecum, the ascending colon, the descending colon and sigmoid colon the positions of these bands are fixed.
The operation involves connecting the appendix to the abdominal wall and fashioning a valve mechanism that allows catheterization of the appendix, but avoids leakage of stool through it. By using the patient’s own appendix for the procedure, doctors can avoid using artificial devices which can be seen and can cause the patient irritation. [ 1 ]
