Describe the internal features of the nasopharynx and oropharynx Identify the components of Waldeyer’s ring Explain why the nasopharynx is kept patent Explain why air does not pass into the esophagus and is directed only into the larynx Explain the functional significance of presence of cartilages in the upper airway passages like the larynx, trachea and bronchi Video by Dr. Akram Jaffar, Department of Medical Neuroscience
