Document Summary
Study questions: explain how the concentration of carbon dioxide in the blood affects its ph, co2 + h2o h2co3 h+ + hco3, as rate of production of co2 exceeds its rate of elimination (higher concentration), the equilibrium shifts to the right and produces more h+, which decreases ph (more acidic, as more frequent & deeper ventilation accelerates elimination of co2, the equilibrium shifts to the left, producing less h+, which increases ph (less acidic, at the beginning of a period of heavy exertion, the rate and depth of breathing increases before carbon dioxide can accumulate in the blood. What is the difference between minute (or pulmonary) ventilation and alveolar ventilation: vital capacity maximum amount of air a person can expel from the lungs after a maximum inspiration (inspiratory reserve volume + tidal volume + expiratory reserve volume, total lung capacity vital capacity + residual volume (volume of air remaining in the lungs after a maximal expiratory effort)
