WebThe extensive network of countercurrent exchange in tunas is often called a “rete mirabile” or wonderful net. It results in a concentration of blood vessels and elevation of body temperature that can help predators catch prey and help prey avoid being caught. WebCountercurrent exchange in an U-type countercurrent exchanger may have two functions: ( 1) trapping of solutes within the system by transfer of solutes from the ascending to the descending limb and ( 2) preventing water from entering the system by short circuiting from the descending to the ascending limb.
