Document Summary
Fluid & electrolyte balance: maintained by ingestion, distribution and excretion. 60% of adult body weight is water. 80% of infant"s body weight is water. Lean tissue contains significant amount of water. Of the body fluid in adults. Interstitial fluid: surrounds the cell and contains no protein. Intravascular fluid: plasma, which is the protein rich fluid that contains large amounts of albumin. Transcellular fluid: csf, synovial, intraocular fluid etc. Other body fluids that contain electrolytes: gastric and intestinal secretions. Compromisation: movement of body fluid between intracellular and extracellular fluid through osmosis, diffusion, active transport and facilitation. Diffusion: continual intermingling of molecules in liquids, gases or solids. Variations in rate of diffusion causes: size of molecules, concentration of solution, temperature of solutions. Filtration: movement of fluid and solutes together across a membrane from one compartment to another. Filtration pressure: compartment pressure that results in the movement of fluid and substances out of the compartment (the difference between the hydrostatic and osmotic pressure)
