  1. Water makes up to as much as _____ of your weight.
    80%
  2. The easiest way to track water gain and loss is to ______.
    weigh the patient.
  3. What are the three ways that substances or particles combine in our body with water.
    Colloids, Suspensions, and solutions.
  4. Dispersions or gels, consist of large molecules that attreact and hold water. they remain uniformly distributed throughout the dispersion and usually do not settle.
    Colloids
  5. Example of colloid.
    protoplasm w/in a cell
  6. Comprise large particles that float in a liquid. mixing of them depends on agitation
    Suspensions
  7. Example of suspension.
    RBC in blood
  8. is a stable mixture of two substances. The substance that dissolves is called the solute and the medium in which it dissolves is called the solvent.
    Solution.
  9. Substance being dissolved.
    • Solute
    • '
    • Medium used to dissolve.
    • Solvent
  10. refers to the ease in which a solute dissolves in a solvent.
    Solubility
  11. The four factors that influence solubility.
    Nature of solvent, nature of solute, temperature, and pressure.
  12. The ease with which substances go into a solution in a given solvent varies widely due to its physical characteristics of matter.
    Nature of a solute
  13. Factor that influences solubility based on the idea that solvents vary widely in their ability to dissolve substances.
    Nature of the solvent
  14. Solubility of most solids increases with temp., but varies inversely w/ ______.
    gases
  15. Solubility of gases in liquids varies directly w/ _______.
    pressure
  16. Is when the amount of solute is small in proportion to its solvent.
    Dilute solution
  17. has the max. amount of solute that can be held be a solvent, at a given temp.
    Saturated solution
  18. If there is excess solute in a solution or the temp cools, what will happen?
    a precipitate will form.
  19. The rate that precipitate forms i the same as the particles ________
    go into the solution.
  20. A solution that contains more solute than a sturated solution, at the same temp and pressure is said to be.
    Supersaturated
  21. Most of the solutions of physiological imprtance in the body are _____
    dilute
  22. Solutes in dilute solution demonstrate many of the properties of gases due to?
    The large spaces between molecules.
  23. The most important physiological characteristic of solutions is their?
    ability to exert pressure.
  24. is the force produced by the mobility of solvent particles under certain conditions.
    Osmotic pressure
  25. Osmotic pressure can be a ________ or _______.
    driving force or an attractive force.
  26. Membrane that permits passage of solvent molecules, but not solute.
    Semipermeable
  27. The number of molecules passing in one directionn must _____ the number of solvent molecules passing in the opposite direction.
    Equal.
  28. Pure solvent is placed on one side of the membrane and a solution on the other. The solvent molecules will move ________ due to the osmotic prssure trying to equalize the concentration on both sides of the membrane.
    Into the solution
  29. If a stronger solution (50%) is placed across a semipermeable membrane from a dilute solution (30%) the attractive osmotic forces will__________.
    pull the solvent until both solutions have the same concentration.
  30. Osmotic pressure depends on ?
    the number of particles in a solution.
  31. Whe effect would increasing the temperature have on osmotic pressure?
    It would also increase.
  32. For every 1C increase, osmotic pressure goes up by?
    1/273
  33. is the degree of osmotic pressure exerted by a solution.
    Tonicity
  34. are sol. that have osmotic pressures equal to the average intracellular pressure in the body.
    Isotonic.
  35. Sol. that has higher osmotic pressure or more tonicity. This will draw water out of cells.
    heypertonic
  36. sol. that has lower osmotic pressure or less tonicity. This will cause water to be absorbed from the sol. into the cells.
    Hypotonic
  37. There are three basic types of physiological solutions that coexist in the body:
    Ionic, Polar Covalent, Nonpolar Covalent
  38. Some of the solute ionizes into separate particles know as ions. this makes it an electrolyte
    Ionc solution ( electrovalent)
  39. Some solutes create ions and it is also an electolyte.
    Polar Covalent solution
  40. no ionization of solute takes place, they carry no electrical charge and are called nonelectrolytes.
    Non-polar covalent solutions.
  41. Are positive charged ions that migrate to a negative electrode called a cathode
    cations(+)
