Electrolytes in body fluids are cations that carry positive charges and anions that carry negative charges. The concentrations of cations and anions in the ecf and icf are different. Osmosis: the diffusion of water from an area of low concentration to an area of high concentration. Osmotic pressure: the amount of hydrostatic pressure needed to stop the flow of water by osmosis. Onocotic pressure: the osmotic pressure exerted by proteins. Osmotic diuresis: the increase in urine output caused by the excretion of substances such as glucose, mannitol, or contrast agents in the urine.
