alimentary
The digestive (alimentary) system (systema digestorium) is a complex of organs whose function consists in mechanical and chemical treatment of food, absorption of the treated nutrients, and excretion of undigested remnants of the food. The structure of the digestive (alimentary) canal (canalis digestorius, s. alimentarius) is determined in the different animals and in man in the process of evolution by the shape-forming effect of the environment (nutrition). The human alimentary canal is about 8-10 m long and is subdivided into the following parts: the cavity of the mouth, the pharynx, the oesophagus, the stomach, and the small and large intestine. HL7 training focuses on these.
