Answer: mucosa

Explanation: the G.I. tract contains four layers: the innermost layer is the mucosa, underneath this is the submucosa, followed by the muscularis propria and finally, the outer most layer - The adventitia. The structure of these layers varies, in different regions of the digestive system, depending on their function.
