Question
Chapter 48.7, Problem 1CS
Summary Introduction
To determine: The relation of countercurrent exchange with the heat exchange in vertebrates.
Introduction: The process of circulation inside the body of an organism is responsible for the transportation of oxygen and various nutrients. The purpose of circulation is to fulfill the demands of the tissues and organs and maintain the internal environment of the body.

- suite of morphological and physiological specializations that permit metabolic heat retention (Carey et al., 1971; Block and Finnerty, 1994; Brill, 1994). More specifically, the RM is positioned medially, or closer to the vertebrae, and is served by a complex network of arteries and veins, which form countercurrent heat-exchanging retia (Carey and Teal, 1966; Carey et al., 1971; Bone and Chubb, 1983; Graham et al., 1983; Block and Finnerty, 1994; Dewar et al., 1994b; Patterson et al., 2011). Interestingly, swordfish are the only teleost species, other than the scombroid fishes, to exhibit a medially positioned RM that is served by a putative vascular rete; but, it is unclear to what degree these specializations function to control RM temperatures, especially during exposure to large and rapid changes in ambient conditions (Carey, 1990; Figure 1a).
