What are the three mechanisms that alone or in combination regulate alveolar pressure? | Musculature, relaxation, airway resistance |
Pressure which is generated entirely by passive forces | Relaxation pressure |
At resting expiratory level, relaxation pressure is... | zero |
During quiet tidal breating, relaxation following inhalation produces ________ relaxation pressure | positive |
Positive relaxation pressure provides the force for ________ exhalation | passive |
The forces of relaxation exert pressure until alveloar pressure is equal to | atmospheric |
Although relaxation pressure is generally considered an expiratory force, it may proide the force for passive inhalation at very ______ lung volumes. | low |
The relaxation-pressure curve graphically depicts the relationship between lung volume and ___________________ pressure. | alveolar |
At lung volumes above 38% vital capacity, inspiration is | active |
At lung volumes above 38% capacity, expiration is | passive |
At lung volumes below 38% vital capacity, inspiration is | active |
At lung volumes below 38% vital capacity, expiration is | active |
