Explanation:
The walls of the alimentary canal from the esophagus to the anus have the same arrangement of tissue layers. These layers are referred to as coats or tunics. There are four tunics or coats of the canal.
From the inside out they are called: the tunica mucosa, the tunica submucosa, the tunica muscularis (or muscularis externa), and the adventitia or tunica serosa.
