1. Chest and Abdomen

2. The Thoracic Cage (Rib Cage)
Rib Cage-12 PAIRS OF RIBS
True Ribs (1-7)
False Ribs (8-10)
Floating Ribs (11 & 12)
Sternum
Costal Cartilage
Thoracic Vertebrae

3. Number the page 1-6 & fill in blanks (start from the top)

4. Structures of Respiration
Upper Respiratory Tract
Nasal cavity
Pharynx
Larynx
Lower Respiratory Tract
Trachea
Bronchial tree

5. Respiratory Pathway 1. Nasal cavity
The internal portion of the nose; it warms, filters, and moistens the air we breathe
2. Oral cavity
The mouth; another place where breathing can take place
3. Pharynx
The throat; extends from the nasal cavity to the larynx and serves as a passageway for both digestive & respiratory systems
4. Larynx
Enlargement at the top of the trachea; passageway for air & houses the vocal cords

6. Respiratory Pathway 5. Trachea
Rigid tube that connects larynx to the bronchial tree; passageway for air & filters air
6. Bronchial Tree
Branched tubes that lead from trachea to alveoli; filters air
7. Lungs
Soft cone-shaped organs that occupy most of the thoracic cavity; contain air passages, alveoli & blood vessels.
Gas exchange occurs in the alveoli of the lungs

7. Respiratory System Function
Supply oxygen (O2) to the cells of the body
Eliminate Carbon Dioxide (CO2) from the body

8. Upper Respiratory Tract: Nasal Cavity
Nasal Conchae
Warms the air
Nasal Cilia
Filters the air
Nasal mucus
Moistens the air

9. Upper Respiratory Tract: Pharynx
The throat
Extends from the nasal cavity to the larynx
Serves as a passageway for both digestive & respiratory systems

10. Upper Respiratory Tract: Larynx
Enlargement at the top of the trachea
Passageway for air
Houses the vocal cords

11. Lower Respiratory Tract: Trachea
Rigid tube that connects larynx to the bronchial tree
Passageway for air
Filters air

12. Lower Respiratory Tract: Bronchial Tree
Branched tubes that lead from trachea to alveoli
Filters air

13. How does the respiratory system filter the air we breath?
Mucus membranes help trap debris & carry it out of body
Cilia filters out dust & other particles
Expelled through coughing, blowing nose, or sneezing
Swallowing

14. Visceral & Parietal Pleura
Visceral pleura covers the lungs
Parietal pleura lines the thoracic wall

15. Pleural Cavity
Contains a small amount of pleural fluid which has 3 main functions:
Lubrication
Reducing heat build-up
Create surface tension to cause lung to remain against the thoracic wall

16. Mechanics of Respiration
Change in thoracic volume
Move the ribs
Move the diaphragm
Air flows from high to low pressure
Difference of pressure in the air vs. the alveoli

17. Mechanics of Respiration: Change in Thoracic Volume

18. Inspiration Ribs elevate Diaphragm moves down (contracts)
Thoracic cavity enlarges
Air is pulled into lungs

19. The Thoracic Cage Movement: Inspiration

20. Expiration Ribs move down Diaphragm moves up (relaxes)
Thoracic cavity gets smaller
Air is pushed out of lungs

21. The Thoracic Cage Movement: Expiration

22. LUNG MODEL http://www.youtube.com/watch?v=JFUu-pn7Qtg
Label the 4 parts of the model, and 3 parts that we can’t see. Then answer the questions.

23. Organs of the abdominal cavity
Stomach-major organ of digestion located in upper left quadrant
Small Intestine- final absorbed food happens here, undigested food moves on to the large intestine.

24. Organs of the abdominal cavity
Liver- largest organ in the abdominal cavity, upper right quadrant, basically a large filter for products of digestion from the small intestine
Kidney- one on either side of the upper quadrants, they filter things and send them to the bladder.

25. Disorders and Injuries

Rib Fracture Spleen Injury
Chest Contusion Hernia
Myocardial Contusion/Aortic Rupture
Sudden Death Syndrome in Athletes
