Answer |
| 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. |

| 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 |
