The dense network of collagen fibers covering the digestive tract in areas without serosa is known as adventitia. The peritoneum is a serous membrane covering the abdominal cavity and its organs, the submucous neural plexus and myenteric neural plexus are nerve networks found in the wall of the digestive tract, and mucosa is the innermost layer of the digestive tract.
