1

water that contains dissolved or suspended substances such as glucose, mineral salts, and proteins

fluid

2

outside the cells

extracellular fluid

3

inside the cells

intracellular fluid

4

divisions of the ECF

intravascular fluid and interstitial fluid (major divisions) and transcellular fluid (minor division)

5

liquid portion of the blood

intravascular fluid

6

located between the cells and outside the blood vessels

interstitial fluid

7

secreted by the epithelial cells

transcellular fluid

8

compound that separates into ions when it dissolves in water

electrolytes

9

measure of the number of particles per kilogram of water

osmolality

10

fluid with the same concentration of non permeant particles as normal blood

isotonic

11

solution is more dilute than the blood

hypotonic

12

solution is more concentrated than normal blood

hypertonic

13

requires energy in the form of ATP to move electrolytes across cell membranes against the concentration gradient

active transport

14

passive movement of electrolytes or other particles down the concentration gradient

diffusion

15

a process by which water moves through a membrane that separates fluids with different particle concentrations

osmosis

16

movement across a membrane, under pressure, from higher to lower pressure

filtration

17

the force of the fluid pressing outward against a surface

hydrostatic pressure

18

an inward-pulling force caused by blood proteins that helps move fluid from the interstitial area back into capillaries

colloid osmotic pressure (oncotic pressure)

19

three processes of fluid homeostasis

fluid intake and absorption, fluid distribution, and fluid output

20

4 organs that fluid output occurs through

skin, lungs, GI tract, and kidneys

21

regulates the osmolality of the body fluids by influencing how much water is excreted in urine

ADH

22

disturbances of the amount of fluid in the extracellular compartment

volume imbalances

23

disturbances of the concentration of body fluids

osmolality imbalances

24

present when there is insufficient isotonic fluid in the extracellular compartment

ECV deficit (hypovolemia)

25

occurs when there is too much isotonic fluid in the extracellular compartment

ECV excess

26

water deficit, body fluids are too concentrated

hypernatremia

27

water excess or water intoxication, body fluids are too diluted

hyponatremia

28

decreased urine output

oliguria

29

Na+

135-145 mEq/L

30

Cl-

98-106 mEq/L
