Question | Answer |
---|---|
Albumin | A major plasma protein, Draws H20 to it |
Aldosterone | Adrenal Gland hormone, Causes Kidneys to reabsorb NA(causing H20 to be pulled to vascular),[] urine, low UO.Anasarca |
ADH | Antidiuretic Hormone from Hypothalamus,Posterior pitituary stores & causes kidneys to return H20,Inc body water, [] urine, low UO |
Colloids | Large solute particles,ex:albumin or protein |
Colloid osmotic pressure | Movement of particles from area of higher {} to lower {} to = pressure |
Electrolyte | substance that when disolves in H20 takes on a charge (+ or -) |
ECF | Extracellular Fluid, outside of cells and in vascular sys |
filtration | Movement of fluid and solute through a membrane due to hydrostatic and osmotic pressure (membrane=cell wall or Capillaries) |
free water | hypotonic solution w/less electrolytes.Warer shifts by osmosis to ICF until = in both ICF and ECF |
Hemoconcentration | plasma is more {} than normal, higher SO |
Hemodilution | plasma is more dilute than normal, lower SO |
Hydorstatis pressure | pushing force of a fluid against the walls of the cell or vas sys |
Hypertonic | lower SO than normal |
Hypervolemia | Fluid vol excess or overload |
Interstitial fluid | , space that surrounds the cell & vasc space (called ECF) |
Isotonic | same SO as normal Plasma |
Oncotic pressure | Pulling force a solution has for H20 due to protien content |
Osmolality | {} of solute (particles) per kg/H20. Creates pulling power for H20 |
Osmolarity | {} of solute (particles) per L/H20. Creates pulling power for H20 |
Osmotic pressure | Pulling fore a solution has for H20 based on its SO.Higher SO=more pulling power for H20 |
Semipermeable membrane | Cell wall or capillary that allows some particles to pass freely. usually small particles. |
Specific Gravity of H20 | a measure of {}. H20=1:1000 (no solutes) |
Specific Gravity of Urine | a measure of {}. Urine gravity=1.01 - 1.03 (Reflects SO) |
Vascular Space | space within the blood vessels. |
