📚 Understanding the pharynx is essential for the TEAS 7 exam! This muscular tube connects the nasal and oral cavities to the esophagus and larynx, playing a role in both digestion and respiration. It has three main parts: 🔹 Nasopharynx – Upper section behind the nasal cavity, primarily for air passage. 🔹 Oropharynx – Middle section behind the oral cavity, involved in both breathing and swallowing. 🔹 Laryngopharynx – Lower section that directs food into the esophagus and air into the larynx.
