6. The Upper Respiratory Tract

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

8. Respiration AKA breathing air moves from pressure to pressure 4 tasks:
pulmonary ventilation
external respiration
respiratory gas transport
internal respiration

9. Respiration Boyle’s law
volume of a gas increases, pressure of the gas decreases
inspiration (inhalation)
expiration (exhalation)

10. Respiration

11. Nonrespiratory Air Maneuvers

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

13. Control of Breathing

14. Respiratory Disorders and Diseases

Respiratory Disorders and Diseases

15. Upper Respiratory Tract Illnesses

16. Upper Respiratory Tract Illnesses
avoiding URIs
cover when sneezing and coughing
wash hands

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

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

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

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

21. Lung Cancer more deaths from lung cancer (than others)
non-small cell lung cancer
more common lung cancer
small cell lung cancer
Chain smokers

22. Carbon Monoxide Poisoning
Oxygen in bloodstream is replaced with CO
Symptoms
Headache
Dizziness, nausea, vomiting
Confusion
Blurred vision
Loss of consciousness
