anaphy

• 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
