Serosa
A serosa lines internal body cavities, forming a parietal layer around the cavity’s exterior wall and a visceral layer over organs protruding into the cavity. A serosa is composed of simple squamous epithelium (mesothelium) overlying a layer of connective tissue. A serosa is equivalent to pleural, pericardial or peritoneal membranes identified in gross anatomy. 200x, 1000x
