F & E CH1 Terms

Terms for Chapter 1

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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
