Fluid, Electrolyte, and Acid-Base Balance Flashcards
(68 cards)
Internal to and relatively surrounds all the cells in the body
Fluid
The intentions
Scientific Knowledge Base
Comprises a substantial proportion of body weight
Water
60% total body weight in Water
Men
Less total body weight in Water
Women
Body fluids
Fluid Distribution
Fluid Compartments
Extracellular Fluid / ECF
Intracellular Fluid / ICF
Intravascular Fluid
Major Division
Interstitial Fluid
Minor Division
Technically full of electrolytes
Composition of Body Fluids
Same tonicity / Concentrated solute
Isotonic Solution
More dilute / Low solute
Hypotonic Solution
More concentrated / High solute
Hypertonic Solution
Movement of Water and Electrolytes
Active Transport
Diffusion
Osmosis
Filtration
Force of fluid pressing outward against a surface / Water-pushing effect
Hydrostatic Pressure
Involves blood containing albumin and other proteins
Colloids
Force of fluid pressing inward against a surface / Water-pulling effect
Oncotic Pressure
Water portion of the fluids
Solvent
Particles dissolved in water
Solutes
Measure in osmoles / 1L of water / 275-295 mOsm/L
Osmolarity
Number of osmoles / kg of water / 275-295 mOsm/kg
Osmolality
Orally through drinking and eating too
Fluid Intake
Among various components
Fluid Distribution
Across the skin, lungs, GI tract, and kidneys
Fluid Output
