Document Summary
Chapter 19: fluid, electrolyte, acid-base imbalances (p 384-392; p408-412). Facilitated diffusion movement of molecules from area of high conc to one of low conc, assisted by. Requires energy to move molecules through membrane against conc. gradient. Movement of molecules from high conc to low. Substances whose molecules dissociate/split into ions when placed in solution membrane carrier molecule. Describe the distribution of body water in different body compartments. State of eq in internal environ of body, naturally maintained by adaptive responses. Hydrostatic pressure f w/in fluid compartment, exerted by water pressure. Sol where solutes more concentrated than they are in intracellular compartment. Sol where solutes less concentrated than they are in intracellular compartment. Sol where conc of solutes = that of intracellular compartment. Measure of total solute concentration per kg solvent *in body. Measure of total solute concentration per l solution *out of body. Movement of water between 2 compartments separated by membrane permeable to water but not to a solute.
