Document Summary
Intracellular fluid (icf): water inside the cell (66%)-nature controlled by nature of the cell membrane do not clinically measure. Extracellular fluid (ecf): water outside the cell (33%)-surrounds cells and creates the environment for cells to exist in. Plasma-20% of ecf-only fluid we can easily measure and look at concentration of electrolytes reflects interstitial fluid contents. Interstitial fluid-80% of ecf-surrounds cells of solid organs. Cat ion=positive ion sodium major cat ion of extracellular fluid, potassium major cat ion of. Balance concept for ecf-input has to equal output regulate by control systems intracellular fluid. Not every pathway used by every substance-i. e. potassium and calcium don"t use metabolic pathway (can"t make those ourselves) Not every pathway controlled by homeostatic control system-i. e. taking in too much water won"t affect gi output. Parameters and receptors-water in the body (in ecf) taking in too much or losing too much will change parameters.
