Chapter 18 - Water, Electrolyte, and Acid-Base Balance 18.1 Introduction (p. 502) A. To be in balance, the quantities of fluids and electrolytes leaving the body should be equal to the amounts taken in. B. Anything that alters the concentrations of electrolytes will also alter the concentration of water, and vice versa. 18.2 Distribution of Body Fluids (p. 502) A. Fluids occur in compartments in the body, and movement of water and electrolytes between compartments is regulated. B. Fluid Compartments (p. 502; Fig. 18.1) 1. The average adult female is 52% water by weight, while a male is 63% water, the difference due to the female's additional adipose tissue. 2. The intracellular fluid compartment includes all the water and electrolytes within cells. 3. The extracellular fluid compartment includes all water and electrolytes outside of cells (interstitial fluid, plasma, and lymph). 4. Transcellular fluid includes the cerebrospinal fluid of the central nervous system, fluids within the eyeball, synovial fluid of the joints, serous fluid within body cavities, and exocrine gland secretions. C. Body Fluid Composition (p. 502; Fig. 18.2) 1. Extracellular fluids have high concentrations of sodium, chloride, and bicarbonate ions, and lesser amounts of potassium, calcium, magnesium, phosphate, and sulfate ions. 2. Intracellular fluid has high concentrations of potassium, phosphate, and magnesium ions, and lesser amounts of sodium, chloride, and bicarbonate ions. D. Movement of Fluid between Compartments (p. 503; Fig. 18.3) 1. Hydrostatic pressure and osmotic pressure regulate the movement of water and electrolytes from one compartment to another. 2.
