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?

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

Lesson 2
Respiration: Mechanics
and Control
Respiration: Mechanics and Control
●
respiration
●
nonrespiratory air maneuvers
●
control of breathing
●
lung volume
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
Respiration
●
Boyle’s law
●
as the volume of a gas increases, the pressure of the gas decreases
Respiration
●
●
inspiration (inhalation)
●
diaphragm and intercostal muscles contract
●
thoracic cavity expands
expiration (exhalation)
●
diaphragm and intercostal muscles relax
●
thoracic cavity shrinks
Respiration
Nonrespiratory Air Maneuvers
Control of Breathing
●
neural factors
●
●
pons and medulla oblongata
chemical factors
●
central chemoreceptors
●
peripheral chemoreceptors
●
mechanoreceptors
Control of Breathing
Lung Volume
●
static
●
●
air volume in lungs
dynamic
●
air volume in lungs based on time
Static Lung Volume
●
tidal volume
●
vital capacity
●
residual volume
●
functional residual capacity
●
inspiratory reserve volume
●
expiratory reserve volume
●
total lung capacity
Dynamic Lung Volume
●
forced expiratory volume in one second
●
forced expiratory volume in one second/forced vital capacity
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.

Overall function
●
Functions of the respiratory system
●
- gas exchange
●
- filter and remove foreign particles from inspired air
●
- humidify and control the temperature of the inspired
air
●
- produce sound (voice)
●
- provide sense of smell
●
- aid in immune defense
●
- conduct air to the lower respiratory tract
Major respiratory organs
●
Nose
●
Pharynx
●
Larynx
●
Trachea
●
Bronchi and Alveoli
●
Lungs
●
Thorax
Lungs 3B
●
