Key Features/Anatomical Relations
The serosa of the stomach is the outermost layer of the stomach which lies against the surrounding organs and tissues in the abdominal cavity (Moore, Dalley and Agur, 2013). The deep surface of the serosa is connective tissue, which adheres to the longitudinal muscular layer of the stomach. The superficial surface of the serosa is an epithelium or mesothelium. This surface is in contact with surrounding organs or the parietal peritoneum.
Function
The serosa of the stomach secretes a serosal fluid. This fluid allows the stomach to slide across neighboring tissues without creating friction and damage.
