  1. Respiration Breathing!

  2. Terminology (1-1-2) • 1. –(o)tomy 8. cochlea- • 2. pulmo- 9. pariet- • 3. alveol- 10. pneum • 4. –ia 11. olfact- • 5. bronch- 12. pleur- • 6. thorac- 13. patho- • 7. scler- 14. in- 15. -pnea

  3. BLESS YOU!

  4. Introduction • Getting O2 to blood • Moving O2 from blood to cell • Moving O2 from cell to Mitochondria

  5. Introduction • Getting CO2 out of cells. • Move CO2 to blood • Get rid of CO2

  6. FUNCTIONS of Respiratory System • 1. Provide gas exchange surface, move air to and from that surface.

  7. FUNCTIONS • 2. Protect surface area from dehydration, temperature changes, and environment.

  8. FUNCTIONS • 3. Defend against pathogenic organisms (disease causing)

  9. FUNCTIONS • 4. Communication ~ Verbal

  10. Activity • GOLD COLDFISH

  11. Respiratory Tract: • Divided into two sections: upper and lower.

  12. Respiratory Tract: • Upper: Conducting passageway • Lower: Respiratory passageway

  13. UPPER RESPIRATORY • Respiratory Epithelium: Ciliated cells that secrete mucus, a mucus elevator.

  14. CILIA

  15. NASAL CAVITY • Nasal cavity is covered with mucus.

  16. NASAL CAVITY

  17. NASAL CAVITY • FUNCTIONS: • 1. Warm air to body temperature

  18. NASAL CAVITY • 2. Filter air for respiration (using cilia and mucus)

  19. NASAL CAVITY • 3. Moisten air for exchange.

  20. NASAL CAVITY • 4. Olfaction: Sense of smell receptors.

  21. NASAL CAVITY • 5. Resonating chamber for Voice.

  22. NASAL CAVITY • External Nares: • Nostrils, coarse hair protects opening.

  23. NASAL CAVITY • Nasal Septum: (134+439) divides nose into left and right chambers. Made of cartilage/bone.

  24. NASAL SEPTUM

  25. NASAL CAVITY • Nasal Conchae: (134) Projections from side, increases surface area and turbulence.

  26. NASAL Conchae

  27. Nasopharynx: Place where nasal cavity joins pharynx • Contains adenoids (pharyngeal tonsils) • Eustachian tubes connect to middle ear.

  28. NASAL CAVITY • Epistaxis: Bloody nose, lots of blood WHY? • Warming air.

  29. NASAL CAVITY • Why do you get a runny nose on a cold day?

  30. NASAL CAVITY • Air condenses when it hits the cold nose surface.
