condition characterized by a proportionate excess of hydrogen ions in the extracellular fluid, in which the pH falls below 7.35
movement of ions or molecules across cell membranes, usually against a pressure gradient and with the expenditure of metabolic energy
condition characterized by a proportionate lack of hydrogen ions in the extracellular fluid concentration, in which the pH exceeds 7.45
colloid osmotic pressure
pressure exerted by plasma proteins on permeable membranes in the body; synonym for oncotic pressure
tendency of solutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration until equilibrium is established
substance capable of breaking into ions and developing an electric charge when dissolved in solution
passage of a fluid through a permeable membrane whose spaces do not allow certain solutes to pass; passage is from an area of higher pressure to one of lower pressure
-below-normal serum concentration of inorganic phorphorus
-muscle pain and tenderness, muscle weakness and paresthesias, confusion, decreased level of consciousness, seizures, anorexia, dysphagia, decreased bowel sounds, possible acute respiratory failure
-deficiency of blood plasma
-signs of fluid imbalance. Dry mouth, cool feet, weak limb pulse, decrease capillary refill, BP, increase pulse (to offset symptoms), serum osmo, albumin, urea.
passage of a solvent through a semipermeable membrane from an area of lesser concentration to an area of greater concentration until equilibrium is established
