Alimentary Systems

An animal’s food, as it is obtained from the environment by the feeding mechanism, is not immediately available for use in the various synthetic and energy-releasing activities of the body. Before it can be utilized in these processes the food must first be broken down into its basic constituents, such as amino acids and monosaccharides, which are water soluble and so can be readily absorbed into the body and transported to the sites of metabolic activity.
