In countercurrent exchange
WebA countercurrent heat exchanger is an arrangement of blood vessels in which heat flows from warmer to cooler blood, usually reducing heat loss. Some animals use body insulation and evaporative mechanisms, such as sweating and panting, in body temperature regulation. How does gas exchange occur in fish? WebMost gas exchange in the respiratory system structures in animals takes place in counter-current arrangement. In short, this means that the medium that delivers the oxygen (air or water) and the structures that the oxygen is delivered to are moving in directions opposite to one another. An example of this is a fish gill system (Figure 2.12).

WebIn a countercurrent exchange system, the blood vessels carrying cooled blood from the flippers run close enough to the blood vessels carrying warm blood from the body to pick up some heat from the warmer blood vessels;thus, the heat is transferred from the outgoing to the ingoing vessels before it reaches the flipper itself.
