  1. aerobic metabolism
    the cellular process in which oxygen is used to metabolize glucose. Energy is produced in a efficient manner with minimal waste products
  2. anaerobic metabolism
    the cullular process in which glucose is metabolized into engergy without oxygen. Energy is produced in a n inefficient manner with many waste products
  3. cardiac output
    the amount of blood ejected from the heart in 1 min. (heart rate x stroke volume)
  4. chemoreceptors
    chemical sensors in the brain and blood vessels that identify changing levels of oxygen and co2
  5. deadair space
    air that occupies the space between the mouth and alveoli but that does not actually reach the area of gas exchange
  6. dehydration
    an abnormally low amount of water in the body
  7. edema
    swelling associated with the movement of water into the interstitial space
  8. electrolyte
    a substance that, when dissolved in water, separates into charged particles
  9. FiO2
    fraction of inspired oxygen; the concentration of oxygen in the air we breathe
  10. hydrostatic pressure
    the pressure within a blood vessel that tends to push water out of the vessel
  11. hypersensitivity
    an exaggerated response by the immune system to a particular substance
  12. hypoperfusion
    inability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. Also called shock
  13. metabolism
    the cellular function of converting nutrients into energy
  14. minute volume
    the amount of air breathed in during each respiration multiplied by the number of breaths per min
  15. patent
    open and clear; free from obstruction
  16. pathophysiology
    the study of how disease processes affect the function of the body
  17. perfusion
    the supply of oxygen to, and removal of wastes from, the cells and tissue of the body as a result of the flow of blood through the capillaries
  18. plasma oncotic pressure
    the pull exerted by large proteins in the plasma portion of blood that tends to pull water from the body into the bloodstream
  19. shock
    the inability of the body to adequately circulate blood to the body's cells to supplythem with oxygen and nurtrients. Also called hypoperfusion. A life-threatening condition
  20. stretch receptors
    sensors in blood vessels taht identify internal pressure
  21. stroke volume
    the anount of blood ejected from the heart in one contraction
  22. systemic vascular resistance (SVR)
    the pressure in the peripheral blood vessels taht the heart must overcome in order to pump blood into the system
  23. tidal volume
    the volume of air move in one cycle of breathing
  24. V/Q match
    ventilation/perfusion match. This implies that the alveoli are supplied with enough air and that the air in the alveoli is matched with sufficient blood in the pulmonary capillaries to permit optimum exchange of oxygen and carbon dioxide
