Here is a paragraph that may help:


(We are studying the mouth)





The mouth's primary role is to help digest food by reducing its size. The mouth includes the tongue, teeth and the hard and soft palates. There also are 3 sets of glands that secrete saliva to aid in chewing food: the parotid glands are located in front of the ears; and the sublingual glands are embeded under the sides of the tongue; and the submaxillary glands are positioned near the rear of the jawbone. The teeth cut and crush food. The tongue acts as a taste organ and it also mixes saliva with food and moves it toward the rear of the pharynx or throat.





Anyways, thanks to those of you who will answer! I really apreciate it!

Two elements of the System would probably be the mechanical breakdown part and the chemical breakdown part...





Its role is to break down food chemically into useable components for the body ie carbs to glucose, protein to amino acids and fats to fatty acids and glycerol.





Part ten may be something like excretion of wastes of before that perhaps aborbtion of water and salts from the Large Instestine?
