Abstract
The alimentary canal is a long tube connecting the oral cavity with the anal canal. The wall has the same basic structure in the entire canal, and the differences reflect the different functions. Chemical and mechanical breakdown of food and liquids is essential to digest food and liquids and to absorb nutrients. The digestion takes place in different stages throughout the alimentary canal and with help from the accessory organs.
