The appendix is also used as a means to access the colon in children with paralysed bowels or major rectal sphincter problems. The appendix is brought out to the skin surface and the child/parent can then attach a catheter and easily wash out the colon (via normal defaecation) using an appropriate solution.
The appendix has a mucosa resembling the colon but is heavily infiltrated with lymphocytes. Transition between the different types of epithelium occurs at the junction between the oesophagus and stomach ; between the stomach and duodenum , between the ileum and caecum , and at the pectinate line of the anus .
It also includes the appendix, which is attached to the cecum. Its length is about 1.5 m, and the area of the mucosa in an adult human is about 2 m 2 (22 sq ft). [19] The longest part of the large intestine is the colon whose main function is to absorb water and salts. [21] The large intestine begins at the cecum, where the appendix is located

The mesoappendix is the portion of the mesentery connecting the ileum to the appendix. It may extend to the tip of the appendix.

Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, and includes histology (the study of the organization of tissues), and cytology (the study of ...

Many books such as Human Anatomy for Artists: The Elements of Form, are written as a guide to drawing the human body anatomically correctly. [4]
