Page 1: Kidney Function and Electrolyte Regulation

  • Dehydration Effects:

    • Lowers blood volume and renal blood flow.

    • Decreases ammonia production, impacting acid-base balance.

  • Kidney Functions:

    • Selectively retain/reject electrolytes to maintain osmolality and blood volume.

    • Retain sodium; excrete potassium.

  • Acid-Base Regulation:

    • Distal tubule forms ammonia, exchanges hydrogen ions for bicarbonate to maintain the carbonic acid-bicarbonate ratio.

  • Endocrine Regulation:

    • Adrenal Glands: Secrete aldosterone, increasing sodium reabsorption and potassium excretion.

    • Pituitary Gland: Releases ADH, promoting water reabsorption to dilute sodium concentration.

    • Parathyroid Glands: Regulate calcium and phosphate balance through PTH.

  • Potassium Functions:

    • Major cellular cation; vital for fluid composition, electrolyte balance, carbohydrate utilization, protein synthesis, nerve conduction, and muscle contraction.

Page 2: Acid-Base Balance and Disturbances

  • Chloride's Role:

    • Major extracellular anion, connected to the body's acid-base status.

    • Deficits in potassium or chloride lead to deficits in the other.

  • Acid-Base Imbalances:

    • Caused by excess/deficit in bicarbonate or carbonic acid.

    • Respiratory Disturbances:

      • Affect carbonic acid through CO2 levels.

      • Respiratory Alkalosis: Caused by rapid breathing; symptoms include anxiety and tetany.

      • Respiratory Acidosis: Due to CO2 retention; symptoms include weakness and confusion.

    • Metabolic Disturbances:

      • Alter bicarbonate levels; controlled by kidney function.

      • Potassium is exchanged for sodium in bicarbonate regulation.

Page 3: Metabolic Disorders and Symptoms

  • Metabolic Alkalosis:

    • Involves excess bicarbonate; symptoms include muscle spasms and tetany.

  • Metabolic Acidosis:

    • Causes: ketone accumulation, renal disease, excessive bicarbonate loss; symptoms include weakness and stupor.

Page 6: Aldosterone and ADH Impact

  • Aldosterone:
