Document Summary
Fluid & electrolytes: human life is suspended in a salt solution (concentration 0. 9%, for life to continue and cells to properly function, body fluids must maintain constant composition of water and electrolytes. Homeostasis: essential to life: maintenance of stable environment for body cells, internal environment: narrow range of normal values, ongoing process: changes constantly occurring in the body. Fluid volume, electrolyte concentrations remain the same: equilibrium: balance. Response (mechanism): compensates for original stimulus, then turns self off. Body and water: 55-60% of adult body weight is water. Higher due to muscle (more h2o) or lower due to fat (less h2o) Females lower: fluctuations in the amount of water in the body can have harmful and even fatal consequences. Functions of water in the body: water is vital to health and normal cellular function, serving as: A medium for metabolic reactions within cells. Body fluids: water and solutes: the term fluid" refers to water and the components it contains.
