Short Answer

  • Describe the oxygen hemoglobin dissociation curve. Explain how it allows for body tissues to receive oxygen and eliminate carbon dioxide wastes.
  • How are the lungs involved in maintaining normal pH of the blood?
  • Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle’s law.
  • Several physical factors that influence the efficiency of pulmonary ventilation are compliance, alveolar surface tension, and airway resistance. Briefly describe each factor.
  • Albuterol is a selective beta-2 adrenergic agonist, which means it specifically activates beta-2 adrenergic receptors on smooth muscle in the airways. How does this improve asthma symptoms?
