Alimentary canal is the term used in zoology for the gut of vertebrates. For humans in particular, see digestive system.
The canal (or tube) carries food through digestion and excretion.[1] Into the tube come various digestive enzymes. Gut flora help digestion, and the production of vitamins. Muscular movements pass the material down the tube. The gut usually has an exit, the anus, by which the animal disposes of solid wastes. Some small animals have no anus and dispose of solid wastes by other means, for example through the mouth.[1]
