Chapter 9: The Respiratory System
Lesson 9.1
Functions and Anatomy of the Respiratory System

4. Anatomy of the Respiratory System
the nose
the nasal cavity
the pharynx
the larynx
the trachea
the bronchi
the lungs

5. Anatomy of the Respiratory System

6. Anatomy of the Respiratory System
the nose
nares
the nasal cavity
conchae
the palate
the sinuses

7. Anatomy of the Respiratory System
the pharynx
tonsils
the larynx
epiglottis
the trachea
C rings

8. Anatomy of the Respiratory System
the bronchi
primary bronchi
bronchioles
the alveoli
surfactant
pores of Kohn
the alveolar capillary membrane

9. Anatomy of the Respiratory System
the lungs
mediastinum
apex
pleural sac
parietal pleura
visceral pleura

10. The Upper Respiratory Tract

11. Review and Assessment
Match these words with 1–4 below: surfactant, apex, epiglottis, conchae.
1. lungs
2. larynx
3. nasal cavity
4. alveoli

12. Respiration: Mechanics and Control
Chapter 9: The Respiratory System
Lesson 9.2
Respiration: Mechanics and Control

13. Respiration: Mechanics and Control
nonrespiratory air maneuvers
control of breathing
lung volume

14. Respiration also known as breathing
air always moves from a higher pressure area to a lower pressure area
four key tasks involved in respiration
pulmonary ventilation
external respiration
respiratory gas transport
internal respiration

15. Respiration Boyle’s law
as the volume of a gas increases, the pressure of the gas decreases

16. Respiration inspiration (inhalation) expiration (exhalation)
diaphragm and intercostal muscles contract
thoracic cavity expands
expiration (exhalation)
diaphragm and intercostal muscles relax
thoracic cavity shrinks

17. Respiration

18. Nonrespiratory Air Maneuvers

19. Control of Breathing neural factors chemical factors
pons and medulla oblongata
chemical factors
central chemoreceptors
peripheral chemoreceptors
mechanoreceptors

20. Control of Breathing

21. Lung Volume static dynamic air volume in lungs
air volume in lungs based on time

22. Static Lung Volume tidal volume vital capacity residual volume
functional residual capacity
inspiratory reserve volume
expiratory reserve volume
total lung capacity

23. Dynamic Lung Volume forced expiratory volume in one second
forced expiratory volume in one second/forced vital capacity

24. Review and Assessment True or False?
1. The pons and medulla control breathing.
2. Static lung volume involves time.
3. Muscles contract in inspiration.
4. Larger gas volume, higher pressure.
5. Gas moves from low to high pressure.

25. Respiratory Disorders and Diseases

27. Upper Respiratory Tract Illnesses

28. Upper Respiratory Tract Illnesses
avoiding URIs
cover when sneezing and coughing
wash hands
don’t touch hands to eyes, nose, mouth

29. Lower Respiratory Tract Illnesses
acute bronchitis
inflammation
pneumonia
infection
tuberculosis

30. Chronic Obstructive Pulmonary Diseases
causes
smoking
living with COPD
stop smoking
purse-lipped breathing

31. Chronic Obstructive Pulmonary Diseases
emphysema
decreased lung surface area
pink puffers
chronic bronchitis
inflammation obstructs airways
blue bloaters

32. Asthma asthma attack inflamed and narrowed airways bronchospasms
caused by allergens or irritants
treatment relaxes muscles to expand airways

non-small cell lung cancer
more common lung cancer
small cell lung cancer
less common lung cancer
