NURS 3234 Lecture Notes - Lecture 6: Bicarbonate Buffer System, Respiratory Alkalosis, Respiratory Acidosis
Document Summary
Intracellular fluid (icf): fluid within cells (70%: extracellular fluid (ecf): fluid outside cells (30%) Total body fluid representing 50% 60% of body weight of normal adult. Ions: cations: positive charge, anions: negative charge, homeostasis: total cations equal to total anions. Fluid balance: solvents: liquids that hold a substance in solution (water, solutes: substances dissolved in a solution (electrolytes and nonelectrolytes) Transporting body fluids: active transport: requires energy for movement of substances through the cell membrane from the, filtration: passage of fluid through a permeable membrane from the area of higher to lower pressure. Isotonic: same concentration of particles as plasma: hypertonic: greater concentration of particles than plasma, hypotonic: lesser concentration of particles than plasma. Intestinal tract: feces: kidneys: urine, skin: perspiration. Fluid intake and losses: about equal in health. A hypertonic solution has a greater osmolarity, causing water to move out of the cells and to be drawn into the intravascular compartment, causing the cell to shrink: true.
