In these animals, heat transfer occurs between arteries reaching zones of potential heat loss (e.g. appendices) and ...

The countercurrent exchanger occurs in the petiole area where the aorta presents many loops thus facilitating heat dissipation via the abdomen (Heinrich and Buchmann, 1986). Robber flies (Diptera: Asilidae) also use their abdomen as a heat dissipater (Morgan and Shelly, 1988). All these anatomical particularities help these …

The two phase regimes ``occurs'' mainly in entrance to the cavity. For example, Figure 13.11 depicts emptying of can filled with liquid. The air is "attempting'' to enter the cavity to fill the vacuum created thus forcing pulse flow. Countercurrent – Alex Sturbaum & Brian Lindsay.

Specifically, the western branch (western North Pacific Subtropical Countercurrent [WSTCC] and western subtropical front [WSTF]) is much …The countercurrent mechanism is a process that allows for the exchange of heat and oxygen between the arteries and veins in the extremities. This process is important because it helps to maintain the body’s core temperature and prevents the loss of heat and oxygen from the extremities.
