What is an electrolyte?
|
A substance that breaks apart into ions or electrically charged partciles when placed in h20
|
TBW in man? woman? newborn?
|
Man=50-60%
woman=45-50%
newborn=70-80%
|
Who has more h20?
young vs old
skinny vs fat
|
Young and the skinny
|
ICF where? and function?
|
Within the cells and its essential for cell fuction and metabolism=cellular medium
|
ECF where? and function?
|
Outside cell its the transportation system bringing h20 nutrients and electrolytes in cell and taking waste out
|
ECF has 3 compartments what are they? and their function?
|
Interstitial fluid lies bw cells, necessary for cellular metabolism
plasma (intravascular) maintains vascular volume
transcellular specialized fluid
|
How much fluid does the avg person take in and put out daily?
|
2500ml in and 1500ml output due to BM, sweat..etc
|
+ charged ion?
|
Cation
|
- charged ion
|
Anion
|
4 major cations?
|
Na, K, Ca, Mg
|
4 major anions?
|
Cl, HCo3 (bicarbonate) HPO4 (phosphate) SO4 (sulfate)
|
Major cation & anion in ECF?
|
Na and Cl
|
Major cation and anion in ICF?
|
K and HPO4 (phosphate)=PP
|
Glucose urea dextrose alcohol creatinine are all organic compounds made up of carbons these are EX of?
|
Nonelectrolytes
|
Functions of electrolytes?
|
Allows movement and reflexes
alows movement of h20 in & out of cell
regulates H+ ions
allows fluid into interstitial spaces
