How long is the pharynx approximately?

The pharynx is approximately 12 cm in length, making it a crucial structure in both the respiratory and digestive systems. It extends from the base of the skull down to the esophagus, playing an essential role in the passage of air to the lungs and food to the stomach.

This relatively short length allows for significant anatomical connections to various surrounding structures, including the nasal cavity, oral cavity, and larynx. The pharynx itself is divided into three regions: the nasopharynx, oropharynx, and laryngopharynx, each serving specific functions in respiratory and digestive processes. Understanding the dimensions of the pharynx is important in the context of various medical conditions, interventions, and anatomical studies.
