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).
The capillaries then join and widen to become venules, which in turn widen and converge to become veins, which then return blood back to the heart through the great veins. Capillaries do not function on their own, but instead in a capillary bed, an interweaving network of capillaries supplying organs and tissues. The more metabolically active a cell or environment is, the more capillaries are required to supply nutrients and carry away waste products.
