Presentation Transcript

  1. Fluid, Electrolyte and Acid-Base Homeostasis Chapter 27

  2. Fluid Compartments

  3. Water Gain and Loss

  4. Dehydration and Thirst

  5. Na+ and Cl- Reabsorption

  6. Body Water Balance

  7. Water Intoxication

  8. Electrolytes in Body Fluids osmolarity -the total concentration of all solute particles in a solution osmolality - the number of solute particles dissolved in one liter of water and is reflected in the solution’s ability to cause osmosis Electrolyte concentrations of body fluids are usually expressed in milliequivalents per liter (mEq/L) = number of electrical charges in 1 liter of solution

  9. Electrolyte and Protein Concentration

  10. Blood Electrolyte Imbalances

  11. Regulation of pH

  12. Regulation of pH

  13. Secretion of H+

  14. Acid-Base Imbalances • Acidosis---blood pH below 7.35 • Alkalosis---blood pH above 7.45 • Compensation is an attempt to correct the problem • respiratory compensation • renal compensation • Acidosis causes depression of CNS---coma • Alkalosis causes excitability of nervous tissue---spasms, convulsions & death

  15. Abnormalities of Acid-Base Balance
