| The oral cavity is the first section of the alimentary tract that recieves food. It provides the digestive functions of prehension, [[Mastication|mastication]] and insalivation and also plays a role in the [[Cardiorespiratory System - Anatomy & Physiology|respiratory system]] through oral breathing when the [[Nasopharynx - Anatomy & Physiology|nasopharynx]] is impaired. | | The oral cavity is the first section of the alimentary tract that recieves food.
