  • Describe the structure of the respiratory membrane (fig. 45.10, see this tutorial on the structure--click the blue links)

Part II

  • Use the oxygen-hemoglobin disassociation curve to predict hemoglobin saturation under varying oxygen partial pressures. Predict how the curve will differ under various pH conditions, under different temperatures, and in animals from different environments. (figs. 45.13, 45.14, 45.15, 45.16, 45.17).
  • Describe how pH, temperature, and amino acid sequence can affect the oxygen-hemoglobin disassociation curve.
  • List the partial pressures of O2 and CO2 in the mammal cardiorespiratory system, describe the rationale for their values, and predict how the values would change under different environmental and physiological conditions (e.g. exercise, changes in breathing rate, changes in altitude, and others) (fig. 45.24)
  • Compare and contrast open & closed circulatory systems know which and identify which organisms that have each type of system (fig. 45.19)
  • Describe the structure of the three primary types of blood vessel (fig. 45.20)
  • Compare and contrast the circulatory systems of fish, amphibians, reptiles, birds, and mammals. Trace the path of blood flow through each system. (fig. 45.22)
