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.
Function of the Pharynx in the Respiratory System. Aside from its work for the digestive system, the pharynx also plays a supporting role for the respiratory system.
