Document Summary

Granular cells- secrete renin, supply na+ and cl- Masa recta- sense flow to sample if have enough na+ and cl- Mucus escalator- needs ciliated epithelium (much less by bronchioles) and mucus producing goblet cells (much less by primary bronchi); move mucus up to throat to spit up or swallow; larynx, trachea, primary, secondary, tertiary, smaller bronchi. Know the different types of pressure associated with the lung-alveolar, intrapleural, atmospheric and transpulmonary. Intra-alveolar: pressure of air in alveoli (inspiration palv < patm, Intrapleural: pressure in pleural cavity, always less than patm. Transpulmonary (transmural): palv - pip, distending pressure of alveoli (how swelled) Afferent constriction: decreases gfr, decreases blood flow into glomerulus, decrease hydrostatic pressure. Efferent constriction: increase gfr, decreases blood flow but increases filtration pressure. Air left in lungs after passive inspiration and expiration; sum of rv and erv. All forces acting on lung and chest wall are balanced.
