Document Summary
Always in a state of elastic tension. Always attached to chest cavity: visceral (surface0, parietal (inner wall, produce pleural fluid between pleural space, fluid holds pm together, act as glue and lubricant. Surfactant phospholipids + hydrophobic surfactant proteins secreted into alveoli by type 2 alveolar cells (pneumocyte) Premature births: surfactant is produced late in fetal life, premature = no surfactant + collapsed alveoli. Prevents permanent damage too much nitrogen treatment is hyperbaric oxygen therapy. Bicarbonate equation: co2 + h2o -> h2co3 + h+ + hco3, co2 + h2o h+ + hco3- Tidal: volume inspired and expired during unforced respiration. Inspiratory reserve: max volume gas that can be inspired in addition to tidal volume: expiratory reserve: max volume of gas remaining in lungs after max expiration. Total lung capacity: total amount of gas in lungs after max inspiration. Vital capacity: max amount of gas expired after a max inspiration.
