13. Review Take out a piece of paper and answer these questions
1.How is breathing related to cellular respiration?
2. How did exercise affect the rate of cellular respiration?
How can bromothymol blue pH help you measure the rate of cellular respiration?

14. A closer look at the mechanics

15. Respiration investigation
In this activity you will measure and monitor breathing rates to better understand respiration, inspiration, and lung capacity

16. Respiration: Mechanics and Control
Chapter 9: The Respiratory System
Lesson 2
Respiration: Mechanics and Control

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

18. 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

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

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

21. Respiration

22. Nonrespiratory Air Maneuvers

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

24. Control of Breathing

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

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

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

28. 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.
