6. Glottis: Protected by voice box (larynx)

7. LARYNX
When swallowing, the glottis is covered by the epiglottis. Preventing food and liquid to enter lungs.

8. LARYNX
VOCAL CORDS: Elastic ligaments that vibrate when air passes through the glottis.

9. Sound determined by length, size and tension.
Vocal Cords
Sound determined by length, size and tension.

10. VOCAL CORDS
1. Short, high tension, thin ligaments vibrate rapidly producing a high pitched sound.

11. Females and young boys generally have these shorter ligaments.
VOCAL CORDS
Females and young boys generally have these shorter ligaments.

12. VOCAL CORDS
2. Large, lower tension, long strands vibrate slower creating a low-pitched sound.

13. Generally males have larger vocal cords then females.

14. VOCAL CORDS

17. Cough Reflex
Involuntary, receptors in glottis respond to particles, liquids and poisons.

18. THEN the abdominal, rib muscles, and diaphragm contract quickly.
COUGH REFLEX
THEN the abdominal, rib muscles, and diaphragm contract quickly.

19. Heimlich Maneuver
Compression of the diaphragm produces air pressure to dislodge the blockage.

20. Inflammation of the vocal cords and/or larynx.
Laryngitis
Inflammation of the vocal cords and/or larynx.
Can cause lower pitch, hoarseness and even loss of voice.

22. Why do boys voices sometimes ‘break’ at the time of puberty?

23. TRACHEA

26. Cartilage rings: C-shaped rings that protect the trachea.
About 20 rings.

27. TRACHEA
Cartilage rings: Prevent airway from collapsing.
Openings face are posterior to allow esophagus to expand.

29. Trachea
Tracheotomy: Incision made into the trachea and a tube is inserted. Air allowed directly into the trachea.

32. TRACHEA
WHY do smokers cough?

33. Two large divisions into each lung.
