For example, the serosa of the uterus is called the perimetrium. Schematic diagram of an organ invaginating into a serous cavity. The pericardial cavity (surrounding the heart), pleural cavity (surrounding the lungs) and peritoneal cavity (surrounding most organs of the abdomen) are the three serous cavities within the human body. While serous ...
The serosa/adventitia are the final layers. These are made up of loose connective tissue and coated in mucus so as to prevent any friction damage from the intestine rubbing against other tissue. The serosa is present if the tissue is within the peritoneum, and the adventitia if the tissue is retroperitoneal.
Tunica muscularis refers to muscular layers in the walls of hollow organs such as the gut, where they are required for peristalsis, and sometimes for sphincters. [7] Tunica serosa is the serous membrane [7] Tunica vaginalis is the serous covering of the testis within the scrotum. [6] Tunica vasculosa could refer
The mesothelium is composed of an extensive monolayer of specialized cells (mesothelial cells) that line the body's serous cavities and internal organs. The main purpose of these cells is to produce a lubricating fluid that is released between layers, [ 4 ] providing a slippery, non-adhesive, and protective surface to facilitate intracoelomic ...
The perimetrium (or serous coat of uterus) is the outer serosal layer of the uterus, derived from the peritoneum overlying the uterine fundus, and can be considered a visceral peritoneum.

The visceral layer of tunica vaginalis of testis (lamina visceralis tunicae vaginalis testis) [4] is the portion of the tunica vaginalis that covers the testis and epididymis. It is the superficial-most of the three layers that constitute the capsule of the testis, with the tunica albuginea of testis situated deep to it.
The outer layer of connective tissue that surrounds an artery, or vein – the tunica externa, is also called the tunica adventitia. To some degree, its role is complementary to that of the serosa, which also provides a layer of tissue surrounding an organ. In the abdomen, whether an organ is covered in adventitia or serosa depends upon whether ...
