  1. 1st Spacing
    normal fluid distribution
  2. 2nd Spacing
    • abnormal accumulation of interstitial fluid
    • ie: edema
  3. 3rd Spacing
    abnormal fluid accumulation in cavaties where it doesn't belong
  4. Acid
    an electrolyte that dissociates into a hydrogen ion (H+) and an anion
  5. Interstitial
    between the cells
  6. Base
    • a substance that combines with H+ and eliminates H+
    • neutralizes an acid by producing water and salt
  7. Normal blood pH
    7.35 - 7.45
  8. What controls pH of internal fluids?
    • Kidneys
    • Respiratory System
    • Buffer System
  9. Elements
    • pure
    • fundamental substance
  10. Compound
    is a sbustance that is formed by two or more different atoms
  11. Atomic Number
    number of protons
  12. Atomic Weight
    protons + neutrons
  13. Isotopes
    • Different form of the same atom
    • same atomic number
    • different atomic weight
  14. Radioisotopes
    unstable nuclei decay and give off particles or energy waves, radioactivity
  15. Chemical Reactions
    the process whereby one chemical sbustance is converted into a different chemical substance
  16. Solution
    combination of solvent + solute
  17. Functions of Water
    • Solvent - carries O2 and dissolves CO2
    • Chemical Reactions - aids in digestion
    • Thermoregulator - evaporation of sweat, takes away large amounts of heat
    • Lubricant
    • Baths cells
    • Protection - CSF
  18. Fluid Compartment
    Intracellular
    2/3 water are inside the cell
  19. Fluid Compartment
    Extracellular
    • 1/3 water is outside the cell
    • intravacular - blood and lymph
    • interstitial - tissue fluid between the cells
    • special cavaties - CSF, bursa, aqeous humor

    • Oxygen
    • Carbon
    • Hydrogen
    • Nitrogen
  21. pH
    • Parts Hydrogen
    • measure of h+ concentration
  22. Valence Shell
    outer electron shell
  23. Ion
    electrically charged atom
  24. Chemical Bonds
    • formed through interaction of atoms
    • the electrical attraction
  25. Ionic Bond
    transfer of electrons
  26. Covalent
    sharing of electrons
  27. Electrolyte
    a sbustance that forms ions when it dissolves in water
