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).
Capillaries, which are the smallest of the blood vessels, are the site of gas exchange...carbon dioxide diffuses out of surrounding cells into the gills to be lost into the en â¦ vironment, and oxygen diffuses from the environment into the gill cells and then surrounding tissues.he gills function like the lungs of a fish, so large numbers of capillaries in these structures function to supply oxygen/get rid of waste carbon dioxide for the organism.
