What happens in the nose, pharynx and larynx?
Air enters your respiratory system through your nose and mouth. From the nose, air flows into the pharynx or throat. The pharynx branches into two tubes. The esophagus leads to the stomach. The larynx leads to the lungs. The larynx is the part of the throat that holds the vocal chords. When air passes across the vocal chords, they vibrate making noise.
