The pharynx (plural: pharynges) is an organ found in vertebrates and invertebrates, though the structure is not universally the same across the species. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system.The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs.he human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization. There are two sets of pharyngeal muscles that act upon the pharynx. These are arranged as an inner layer of longitudinal muscles and an outer circular layer.
