Body fluids
Chemical composition of body fluids
K+ ion
high in intracellular
low in extracellular compartments
small diff between interstitial and plasma
big diff between extracellular and intracellular
Ca++ ions
none in intracellular
present in extracellular compartment
small diff between intracell and extracell
Na+ ions
low in intracellular compart.
high in extracellular compartment
small diff between interstitial and plasma
big diff between extracellular and intracellular
Cl- ions
large diff between intracell and extracell
high in extracellular compartments
low in intracellular compartments
small diff between extracellular compartments
proteins ions
low in extracellular compartment
higher in intracellular compartment
small diff between intracell and extracell
small difference within extracell compartments
difference in ion concentration is due to the semi permeable nature of the plasma membrane
major fluid compartments
intracellular fluid compartment(ICF)
everything inside the cells
67% of TBW
extracellular fluid compartment(ECF)
includes everything outside of the cell and is part of the body's internal environment
further division
interstitial fluid compartment
fluid directly outside cells
26.4% of total body water (TBW)
plasma
watery portion of blood
6.6% of TBW
is a colloidal solution
liquid with suspended substances that do not settle out of solution
these substances are plasma proteins
globulins
fibrinogen
albumins
is 92% water, 8% other substances (proteins, ions, gases, etc.)
plasma volume remains pretty constant as water intake matches water loss in the body
The total body water in all compartments is 42 L
