Fluid, Electrolyte, and Acid-Base Balance Flashcards
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
Regulates osmolality of the body fluids
Antidiuretic Hormone
Regulates ECF volume through sodium and water excreted in urine upon blood pressure
Renin-Angiotensin-Aldosterone Hormone
Regulates ECV through sodium and water excreted in urine upon hormones
Atrial Natriuretic Peptide
