Unformatted text preview: since electrolytes dissociate into 2 or more ions in water, they have the greatest ability to cause osmotic movement of water o Comparison of Intracellular & Extracellular Fluids extracellular fluid : chief ions are sodium cations (positive ions) & chloride anions (negative ions) intracellular fluid : chief ions are potassium cations & phosphate anions (negative ions) cellular ATP-dependent sodium-potassium pumps maintain balance (keep sodium ions outside cell & potassium ions inside cell) since ions are generally small molecules, proteins & large nonelectrolytes (mostly lipids) are the bulk of the mass of dissolved solutes in body fluids- Fluid Movement Among Compartments o exchanges between plasma & interstitial fluid occur across capillary membranes o exchanges between interstitial & intracellular fluids occur by passive transport (osmosis & diffusion) & active transport Page1...
