3. made up of 2/3 intracellular
(40%) of water

4. made up of 1/3 extracellular
(20%) of water

5. what two things Intravascular and interstitial
make up extra-
cellular fluid?

6. what % of in- 25%
travascular is in
the extracellu-
lar?

7. what % of inter- 75%
stitial is in the ex-
tracellular?

8. who has more men
water, men or
women?

9. who has more pediatric
water, elderly or
pediatric?

10. why does total decreased free fat and muscle mass
body water de- renal decline
crease as we diminished thirst perception
age?

11. Starling forces forces affecting movement of fluid between cells and
spaces


,12. net filtration forces favoring filtration minus forces opposing filtration

13. Osmolarity concentration of osmotically active particles in a solution

14. isosmotic solutions with the same concentrations of solute particles
(osmolarity)

15. hyposomotic solution with lower osmotic pressure. lower outside

16. hyperosmotic solution with higher osmolarity. higher inside.

17. isotonic two solutions with the same osmotic pressure

18. Hypotonic when comparing two solutions, the solution with the less-
er concentration of solutes within the cell

19. Hypertonic when comparing two solutions, the solution with the
greater concentration of solutes within the cell

20. Forces favoring Capillary hydrostatic pressure (blood pressure) and inter-
filtration stitial oncotic pressure (water-pulling)

21. Forces favoring Plasma (capillary) oncotic pressure (water-pulling)
reabsorption Interstitial hydrostatic pressure

22. edema accumulation of fluid within the interstitial spaces

23. causes of edema increased capillary hydrostatic pressure (increased BP),
decrease of plasma oncotic pressure,
obstruction of lymphatic circulation,
increased capillary permeability
