The pharynx is an anatomical structure that functions in both respiration and digestion in the human body. In this lesson we will investigate the anatomy and physiology of the pharynx to gain an understanding of its importance and how it works.
Definition of Pharynx. The pharynx is the body cavity that connects the nasal and oral cavities with the larynx and esophagus. It is commonly referred to as the throat. The pharynx is part of both the digestive and respiratory systems.he pharyngeal tonsils, or adenoids, are located on the posterior wall of the nasopharynx. The oropharynx is behind the soft palate of the mouth and is below the nasopharynx.
