Fluid transport
Diffusion –solute will spread from an area of
higher concentration to an area of lower
concentration in a solution (solute movement)
Osmosis-osmotic pressure is the force that
drains the solvent from an area of less
concentration of solute to an area of
higher concentration of solute through a selectively permeable membrane .(solvent movement)
Filtration –movement of solute and solvent by hydro-static pressure from an area of higher pressure to lower pressure .
Hydro static pressure-pressure exerted by the wt of a
solution .
Osmolality-no of osmotic-ally active particles
/kg of water
Normal
osmolality of plasma is 270-300 milli osmo/kgof water.
