    • the organs and structures of the respiratory system are responsible for the exchange of the respiratory gases
    • the respiratory gases are oxygen and carbon dioxide
    • oxygen is delivered to all body cells in exchange for carbon dioxide
    • oxygen is a gas essential for life
    • carbon dioxide is a waste product
    • cardiovascular system assists in gas exchange by providing blood vessels, the pathways for transporting gases
    • effects of failure or deficiency in RS & CS:
      • disruption of homeostasis
      • oxygen starvation in tissues
    • the effects of failure and deficiency in RS & CS may result in death
    • the lungs and airways bring in fresh, oxygen-enriched air and expel waste carbon dioxide by a process called breathing or ventilation
    • breathing is an important method of regulating the pH of the blood, thereby maintaining homeostasis
    • breathing process begins with inhalation
