The importance of the serous portion of the saliva. Introduction: Saliva is composed largely by the water (97-99.5%), so it is considered as hypo-osmotic. The osmolarity of the saliva lies on the glands, which upon activation responsible for the salivation. The saliva is composed of various solutes, digestive enzymes, defence molecules and metabolic waste. The glands responsible for these secretions are known as salivary glands, these glands are categorized on the basis of their secretions.
