ABSTRACT
The digestive system consists of those body structures and organs that function in the prehension, transport, and breakdown of food, in the absorption and temporary storage of absorbed nutrients, and in the discharge and elimination of alimentary waste products from the body. The pharynx represents an intersection between the digestive and respiratory systems. The oropharynx extends caudally to the base of the epiglottic cartilage, where it is continued by the laryngopharynx. Except during swallowing, the laryngopharynx is closed by the pharyngeal constrictor muscles, which may be assisted in this function by engorgement of the pharyngeal venous plexus located in the wall of the laryngopharynx. The alimentary canal consists of a musculomembranous tube that extends from the laryngopharynx to the anus. Typical of the carnivore, the intestines of the cat are not highly modified and constitute a relatively simple tubular continuation of the alimentary canal from pylorus to anus.
