Quizplus · Accepted Answer

The submucosa is the layer of the alimentary tube that contains Meissner's plexus, which regulates secretions. The mucosa is the layer that lines the lumen and is responsible for absorption and secretion. The external muscle layer (also known as the muscularis externa) is responsible for propelling materials through the alimentary tube. The mesentery is a membrane that connects the digestive organs to the abdominal wall.
