Respiratory System
Respiratory volumes and capacities
**Four respiratory volumes
**
Inspiratory Reserve Volume (IRV) is the volume that can be inhaled at the end of a resting inspiration. (3,000 mL)
Expiratory Reserve volume (ERV) is the volume of air that can be exhaled at the end of a resting expiration (1,100 mL)
Tidal Volume (TV) is the volume of the air that enters or leaves the lungs during a respiratory cycle. (500 mL)
Residual Volume (RV) is the volume of air that remains in the lungs even after a maximal expiration. (1,200 mL)
Vital Capacity (VC) is maximum volume of air that can be exhaled after taking the deepest breath possible
VC = TV + IRV + ERV
(4,600 mL)
Inspiratory capacity (IC) is the maximum volume of air that can be inhaled following exhalation of resting tidal volume
IC = TV + IRV
(3,500 mL)
Functional Residual Capacity (FRC) is the volume of air that is remained in the lungs following exhalation of resting tidal volume
FRC = ERV + RV
(2,300 mL)
Total Lung Capacity (TLC) is the total volume of air that the lungs can hold
TLC = VC + RV
varies with age, gender, body size
(5,800 mL)
Upper respiratory structures and functions
Contain nose, nasal cavity, sinuses, and pharynx
Nose: The nostrils provide openings for entrances and exit of air which the
Layers of the pleurae
Visceral Pleura is the inner layer that's attached to the surface of each lung
Parietal Pleura is the outer layer and is lined with the thoracic cavity
Lower respiratory structures and functions
Contains larynx, trachea, bronchial tree, and lungs
Major functions of the respiratory system
Compare and contrast the mechanism of inspiration and expiration
