01 / Location & anatomical relationships
Behind your nose and mouth, leading down into your neck.
02 / Structure & organization
The pharynx is divided into nasopharynx, oropharynx and laryngopharynx. It is a muscular passage shared by respiratory and digestive pathways. During swallowing, coordinated elevation and closure mechanisms direct the bolus toward the esophagus.
03 / Function
It helps move air toward your windpipe and food toward your esophagus.
04 / Mechanism
The throat is a shared route for air and swallowed food. A coordinated swallow temporarily protects the airway while food is directed into the esophagus. Muscles squeeze in sequence to keep the mouthful moving.
Part of a bigger picture
The throat belongs in our torso & skin collection. Explore the nearby parts to see how this area of the body fits together.

Connect structure with function
The throat is a regional term, not a single organ. Distinguish the pharynx behind the oral cavity from the larynx, which guards and produces sound at the airway entrance.
Check your understanding
Locate the throat in relation to its neighbors. Explain how the structural features described above support its function, then distinguish it from a nearby structure with a different role.
