Pharynx: passageway for food to the esophagus and air to the larynx 29. advantages of shared passageway of the pharynx: 1) air can enter throughthe mouth when nasal cavity is obstructed 2) allows for relatively normal breathing while eating 3) greater air intake during heavy exercise that requires more gas exchange 30. soft palate: the muscular posterior portion of the palate that closes off thenasopharynx during swallowing or speaking 31. glottis: an opening in the larynx where vocal folds are located 32. Larynx: voice box;passageway for air moving from pharynx to trachea; containsvocal cords 33. vocal folds (true vocal cords): at
