Quizplus · Accepted Answer

Specialized cells in the mucosal lining of the GI tract produce and release secretions needed for digestion. Accessory organs such as the liver, pancreas, and gallbladder also produce and release secretions that aid in digestion. The submucosa, muscularis, and serosa are layers of the GI tract that do not directly produce secretions for digestion.
