Respiratory System Katherine Contreras Period 6
Major functions
External respiration
Gas transport
breathing
Cellular respiration
removes particles from
incoming air
Internal respiration
provides vocal sounds
regulates blood pH
regulates temperature and water content of the air
helps sense of smell
Layers of the pleurae
Lower respiratory structures and functions
Bronchial Tree- conducts air from trachea to alveoli/ mucous
lining continues to filter incoming air
Lungs- contains air passages, alveoli, blood vessels,
connective tissues, lymphatic vessels, and nerves
Trachea- passageway for air/ mucous lining continues to
filter particles from incoming air
Larynx- passageway for air, prevents foreign objects from
entering trachea, and houses vocal cords
Upper respiratory structures and functions
Nasal Cavity- conducts air to pharynx, mucous lining filters,
warms, and moistens incoming air
Pharynx- passageway for air moving from nasal cavity to larynx and for food moving from oral cavity to
esophagus
Sinuses- reduce weight of skull and serve as resonant
chambers
Nose- provide entrance to nasal cavity
Volume and Pressure relationships in thoracic cavity
Disorders of the respiratory system
Pneumonia- Bacterial/ viral infection of lungs
Lung Cancer- uncontrolled cell growth + development of tumors in the lungs
Tuberculosis- bacterial infection in respiratory system
Seasonal Flu- Viral infection
COPD-chronic obstructive pulmonary disorder
Compare and contrast inspiration and expiration
expiration
Insipration
Respiratory volumes and capacities
Expiratory reserve volume (ERV)-1,100 mL- Max volume of air that can be exhaled at the end of a resting
expiration
Residual volume (RV)-1,200 mL- Volume of air that remains in the lungs even after a maximal expiration
Inspiratory reserve volume (IRV)-3,000 mL- Maximal volume of air that can be inhaled at the end of a resting inspiration
Vital capacity (VC)-4,600 mL- Max volume of air that can be exhaled after taking the deepest breath possible: VC = TV + IRV + ERV
Tidal volume (TV)-500 mL- Volume of air moved in or out of the lungs during a respiratory
cycle
Inspiratory capacity (IC)- 3,500 mL- Max volume of air that can be inhaled following exhalation of resting tidal volume: IC = TV + IRV
Functional residual capacity (FRC)- 2,300 mL- Volume of air that remains in the lungs following exhalation of resting tidal volume: FRC = ERV + RV
Total lung capacity (TLC)-5,800 mL - Total volume of air that the lungs can hold: TLC = VC + RV
