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).
At this point, there is no net change of volume: Fluid moves out of the capillary at the same rate as it moves into the capillary. Near the venous end of the capillary, the CHP has dwindled to about 18 mm Hg due to loss of fluid. Because the BCOP remains steady at 25 mm Hg, water is drawn into the capillary, that is, reabsorption occurs.
