Inspiratory reserve volume- forced inspiration Expiratory reserve volume- forced expiration Residual volume- remaining air after forced expiration Vital capacity- inspiratory reserve+ tidal + expiratory reserve= maximum amount of air a person can exhale Inspiratory capacity- tidal +inspiratory reserve= maximum air that can be inhaled Functional residual capacity- expiratory reserve + residual = air remaining in lungs after resting expiration Total lung capacity- vital capacity + residual volume 36) partial pressures and diffusion in alveoli and capillaries Gases move from high to low pressure Partial pressure- pressure of each gas in atmosphere 37) transport of oxygen and carbon dioxide in blood Oxygen Oxyhemoglobin- oxygen dissolves in blood and combines with the iron or hem part of hemoglobin Plasma- 2% of oxygen dissolves in the liquid portion of blood Carbon dioxide 1) Bicarbonate ions- carbon dioxide reacts with water, dissociates in RBC, comes out as bicarbonate ions and hydrogen, once again reacts to form carbon dioxide and water Carbonic anhydrase- enzyme which speeds up the reaction of carbon dioxide and water 2) Carbaminohemoglobin- carbon dioxide attaches onto the globin or amino acid part of hemoglobin 3) Plasma- carbon dioxide dissolved in plasma Causes of release Oxygen- partial pressure of oxygen is low, partial pressure of CO2 is high, acidity is high, and temp is high Carbon dioxide- partial pressure of CO2 is low, partial pressure of O2 is high
