Functions of fluid in the body:
|
- Maintain temperature - Maintain cell shape - Transport materials - MAINTAIN HOMEOSTASIS! |
|
|
6 fluid compartments:
|
1- EXTRACELLULAR - outside cells 2- INTRACELLULAR - inside cells 3- INTERSTITUAL - between cells 4- INTRAVASCULAR - inside blood vessels (ECF) 5- EXTRAVASCULAR - outside blood vessels 6- TRANSCELLULAR - within hollow spaces (CSC. pleural cavity, lymph system). |
|
|
Anion
|
Electrolyte that generates positive charge - Chloride - Phosphate - Bicarbonate |
|
|
Cation
|
Electrolyte that generates negative charge - Sodium - Calcium - Potassium - Magnesium |
|
|
Main extracellular electrolytes:
|
- SODIUM - abundant in ECF - CHLORIDE - BICARBONATE |
|
|
Main intracellular electrolytes:
|
- MAGNESIUM - POTASSIUM - PHOSPHATE |
|
|
Sensible and insensible fluid loss:
|
SENSIBLE = can be measured INSENSIBLE = cannot be measured |
|
|
Isotonic
|
- Same concentration of particles to ECF so prevent fluid shift between intra and extra-cellular areas. - Most widely used |
|
|
Hypertonic
|
- COLLOIDS - More highly concentrated than ECF - Fluid is pulled from cells into bloodstream - Causes cells to shrink |
|
|
Hypotonic
|
- CRYSTALLOIDS - Less concentrated than ECF - Fluid pulled from bloodstream into cells, causeing cell to swell - danger of lysis (breakdown of cell membrane) so rarely used |
