How to differentiate function and non-function interstitial fluids Function:Taking part in modulating the balance of body fluids. How to differentiate function and non-function interstitial fluids Non-function: Fluids in cavity in normal status.Including cerebrospinal ,joint,pericardium and abdominal cavity fluids Third Space Definition: Pathophysiologiclly, relatively nonfunctional extra cellular fluid.Mainly for the change of quantity of functional and nonfunctional ECF. Third Space Distribution: exudates in burns; ascites; soft tissue injuries. bowel wall;peritoneum;infected lesions. Attention: not confused with the nonfunctioning components from interstitial fluid. Pressure leading to the shift of water through semi-permeable membrane Definition the number of osmotically active particles or ions per unit volume. Unit : milliosmoles per liter （mOsm / L） Relation between Osmotic pressure and distribution of body fluid Osmotic Pressure： Crystal OP and Colloid OP Plasma Crystal OP : [Na+] contributes to a major portion of OP Relation between Osmotic pressure and distribution of body fluid Plasmatic Colloid OP： Plasma protein contributes a force leading to distribution of ECF Interstitial Crystal OP： Contributes to the shift of extracellular and intracellular water The Regulation of Body Fluid Balance Maintaining normal osmotic pressure Maintaining normal concentration Integral dose of natrium Maintaining normal Volume (Blood-volume) The Regulation of Body Fluid Balance Maintaining osmotic pressure The Regulation of Body Fluid Balance Maintaining the concentration Integral dose of natrium The Regulation of Body Fluid Balance Volume regulation(Blood-volume) Classification of body fluid change( Four Types ) Volume Changes(ECF) Volume Deficit Volume Excess Concentration Changes Hyponatremia Hypernatremia Classification of body fluid change( Four Types ) Mixed volu
