Why would a system such as the countercurrent heat exchanger evolve? A. Reduce the loss of heat by distal appendages B. Maintain the continuity of nutrients to distal appendages C. Maintain blood pressure throughout the distal appendages D. Reduce the loss of fur by distal appendages
It has to be A since this is the only one with heat in the answer. A mechanism for homeostatic control of temperature.
It's A. Countercurrent heat exchange is a way some organisms conserve body heat.
