What is it: Not a fish to take lightly, Cobia will put up a fight with even the most seasoned anglers. As the Gulf Coastâs king of nicknamesâtheyâve been called âcabio,â âling,â âlemonfishâ and âcrabeaterââan average Cobia runs about 20-30 pounds, but theyâve been roped in at sizes of up to 100 pounds.
Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration. Osmotic Pressure. The net pressure that drives reabsorptionâthe movement of fluid from the interstitial fluid back into the capillariesâis called osmotic pressure (sometimes referred to as oncotic pressure).
When the vesicle is attached to the plasmalemmal membrane, it has an opening of approximately 20-30 nm. The transport of materials across capillary walls occurs mainly by two processes: diffusion and filtration. The driving potential for diffusion is the concentration gradient. The driving potential for filtration (or reabsorption) is the pressure gradient (fluid mechanical pressure and colloidal osmotic pressure).
