Show Answers:

  1. colloids
    protein substances that increase the colloid oncotic pressure
  2. colloid oncotic pressure
    • another name for oncotic pressure
    • form of osmotic pressure exerted by protein in blood plasma that normally tends to pull water into the circulatory system
  3. crystalloids
    substances in a solution that diffuse through a semipermeable membrane
  4. dehydration
    • excessive loss of water from the body tissues
    • accompanied by an imbalance in the concentrations of essential electrolytes, particularly sodium, potassium, and chloride
  5. edema
    the abnormal accumulation of fluid in interstitial spaces
  6. extracellular fluid (ECF)
    that portion of the body fluid comprising the interstitial fluid and blood plasma
  7. extravascular fluid (EVF)
    fluid in the body that is outside the blood vessels
  8. hydrostatic pressure (HP)
    pressure exerted by a liquid
  9. hyperkalemia
    • an abnormally high potassium concentration in the blood
    • most often due to defective renal excretion but can also be due to excessive dietary potassium
  10. hypernatremia
    • an abnormally high sodium concentration in the blood
    • may be due to defective renal excretion but is more commonly caused by excessive dietary sodium or replacement therapy
  11. hypokalemia
    condition in which there is an inadequate amount of potassium in the bloodstream
  12. hyponatremia
    • condition in which there is an inadequate amount of sodium in the blood stream
    • caused by inadequate excretion of water or by excessive water intake
  13. Interstitial fluid (ISF)
    the extracellular fluid that fills the spaces between most of the cells in the body
  14. Intracellular fluid (ICF)
    • fluid located within the cell membranes throughout most of the body
    • contains dissolved solutes that re essential to maintaing electrolyte balance and healthy metabolism
  15. Isotonic
    • having the same concentration of a solute as another solution
    • same osmotic pressure
  16. osmotic pressure
    pressure produced by a solution necessary to prevent the osmotic passage of solvent into it when the solution and solvent are separated by a semipermeable membrane
  17. serum
    clear, cell-free portion of the blood from which fibrinogen has also been separated during the clotting process
