    1. Why is it important to study fluid and electrolytes???

    2. WATER

    3. SOLUTES Electrolytes Nonelectrolytes

    4. Body Fluid Compartments ICF Intracellular ECF Extracellular ~Intravascular ~Interstitial ~Transcellular

    5. Factors affecting fluid movement Urine formation Oxygenation of tissue Acid-base balance Cell membranes are selectively permeable

    6. Transport Processes Diffusion Osmosis Filtration Active transport

    7. Concentration of Body Fluids Osmolarity serum - 280-295mOsm/kg urine 500-800mOsm/L Concentration of body fluids Changes in ECF osmolarity causes changes in volume of cells due to osmotic shifts of water

    8. Concentration of Body Fluids Decrease ECF osmolarity water shifts ECF to ICF cell swells

    9. Concentration of Body Fluids Increase ECF osmolarity water shifts ICF to ECF cells shrink

    10. TONICITY of IV FLUIDS Isotonic (between 250-375 mOsm/L) Hypotonic Hypertonic

    11. Regulation of Body Fluids Fluid Intake - Thirst Kidneys HORMONAL ADH Renin-Angiotensin-Aldosterone System Atrial Natriuretic Factor

    12. Regulation Intake and Output

    13. Regulation - Kidney Regulate volume and osmolality of ECF fluids by regulating water and electrolyte excretion 135-180L of plasma per day is filtered by kidneys only 1.5L of urine is excreted

    14. Regulation ADH and Thirst
