Pharynx

The pharynx is a muscular tube located behind the nose and mouth that serves as a passageway for air, food, and liquids. It connects the nasal cavity and mouth to the larynx and esophagus. During breathing, it directs air into the windpipe and lungs. When swallowing, the pharynx helps guide food and liquids into the esophagus, preventing choking. It also plays a role in speech by helping produce sounds. The pharynx is an essential part of the respiratory and digestive systems, ensuring the proper routing of airflow and ingested materials.
