Document Summary

Forces and movements of breathing: passive forces, active forces, movements of the rib cage wall, movements of the diaphragm, movements of the abdominal wall. Forces (diagram: passive: no muscles are involved, active: muscles are involved, p= f/a. Inside the lungs (intra) pleural o o o o o o o o o o. Between visceral and thoracic (costal) pleurae: abdominal. Movements of the rib cage wall: circumferences of rib cage wall increases when we inhale, circumferences of the rib cage wall decreases on exhalation, possible because of 2 joins. Costovertebral joints o o: costo-central, costo-transverse, pump handle (diagram, buckle handle. Relative movements: palv influences by percentage contact rc and ab have with lungs, rc = 75% of contribution, ab = 25% of contribution. Airway open (inhalation); increase the volume in the lungs. Lung capacities: p 1/v; boyle"s law o. Can measure lung volume with: wet spirometer (diagram, dry spirometer, computerized spirometer, pneumotachograph, pressure, shape.
