Overview: serosa

Most of the small intestine protrudes into an internal body cavity (peritoneal) and is, therefore, covered by a serosa:  a connective tissue layer and its overlying simple squamous epithelium (mesothelium).  A portion of the duodenum is retroperitoneal and is surrounded only by a connective tissue layer, the adventitia where it contacts the posterior body wall.  (For a more detailed review of these two layers, see the General Concepts:  Membranes.)  800x
