Which organ is included in the alimentary canal?

Explanation:
The alimentary canal is the continuous tube that digests and transports food from the mouth to the anus. The esophagus is included because it is the muscular conduit that moves swallowed food downward to the stomach through peristaltic waves, forming part of that main tube. The other organs—liver, pancreas, and gallbladder—are accessory digestive organs; they help digestion by producing bile or enzymes, but they are not part of the main alimentary canal itself. So the esophagus is the organ that belongs to the canal.
