Which term denotes the structure that extends from the mouth to the anus?

Explanation:
Alimentary canal is the continuous tube that runs from the mouth to the anus. It includes the esophagus, stomach, and the intestines, through which food is ingested, digested, and nutrients absorbed as it moves along. This is different from surface area, which is a measurement of how much exposed area a structure has; chyme, the semi-liquid mass of partly digested food found in the stomach and intestines; and accessory organs like the liver, pancreas, and glands, which aid digestion but are not part of the main digestive tube itself.
