Intake for adult is 2500/day.

Out put is through kidneys, lungs, skin, feces, and sweat

*water intake must equal out put to maintain Fluid balance.

Water movement from areas of low solution concentration to areas of high solute concentration.

Types:

Hypertonic ( Water will move from interstitial fluid to plasma)

Hypotonic (Water moves from plasma to interstistial fluid)

Isotonic (no net fluid shift)

Expands intravascular fluid volume(plasma) without causing major fluid shifts between compartments

*

Proteins, starches, or other large molecules  that remain in the blood because they are too large to cross the capillary membranes.

-will draw water molecules from cells and tissues into the plasma ( like hypertonic solutions)

-used in treading hypvolemic shock due to burns, hemmorrahage, or surgery.
