==Introduction==

The anatomy of the alimentary system begins rostrally with the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]], which is the first section of the alimentary tract that recieves food. It provides the digestive functions of prehension, mastication and insalivation and also plays a role in the respiratory system through oral breathing when the nasopharynx is impaired. The oral cavity or mouth, includes accessory structures - [[Oral Cavity - Salivary Glands - Anatomy & Physiology|the salivary glands]], projecting structures - [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|the teeth]], and [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]] and the boundaries enclosing the oral cavity; the [[Lips - Anatomy & Physiology|lips]], [[Cheeks - Anatomy & Physiology|cheeks]], [[Soft Palate - Anatomy & Physiology|soft]] and [[Hard Palate - Anatomy & Physiology|hard palates]], and the [[Oral Cavity - Oropharynx - Anatomy & Physiology|oropharynx]].

In anatomical terms, the oropharynx is common to both the alimentary and the respiratory system, and the hard and soft palate forms the boundary between the oral and the nasal cavities in many species.
