It contains the teeth and tongue and receives the secretions from the salivary glands. Chewing by teeth cuts, smashes, and grinds food, making it easier to swallow. The tongue tastes the food shapes the food into a ball called a bolus, Salivary glands deliver saliva to the oral cavity through ducts. It is a viscous mixture of water, salts, salivary amylase (an enzyme that initiating breakdown of carbohydrates) and electrolytes(bicarbonate and phosphates), lysosome(antimicrobial).Bolus is pushed by the tongue into the pharynx, moved along through the alimentary canal by the rhythmic muscle contractions of peristalsis, and moved into and out of the stomach by sphincters.
