Human Phys 6.2 Flashcards
A
Alveolar
a
Arterial
Tidal volume
Breathing normal (500mL)
Inspiratory reserve volume
Breathing in as much air as possible (3000 mL)
Expiratory reserve volume
Breathing out as much as possible (1200mL)
Residual volume
The air left over in lungs after you have breathed out as much as you can (1200mL)
Lung capacity
2 or more lung volumes added together
Inspiratory capacity
Tidal volume + inspiratory reserve volume
Vital capacity
IRV + TV + ERV
Functional residual capacity
ERV + RV
Total lung capacity
IRV + TV + ERV + RV
Functional residual capacity line
Represents equilibrium point for your lungs (in between TV and ERV)
Dead space
Volume of airways and lungs that does not participate in gas exchange
Anatomical dead space
Volume of the conducting airways (150 mL of the 500mL of TV)
Physiological dead space
Total volume of lungs that does not participate in gas exchange
