Salivary amylase aids in digestion of polysaccharides. Remember that digestion actually begins with chewing (mastication), which can be distinguished as mechanical and not chemical digestion.
The salivary glands of the oral cavity secrete saliva (hence the name). 98% is water and 2% is electrolytes, mucus, glycoproteins, enzymes, and other compounds such as the antibody IgA (immunoglobin A). Mucus, lysozyme, and IgA aid in immune response.
