Thermal role of a blood vessel running through a temperature gradient.
A mathematical model of a blood vessel running through a linearly varying temperature field suggests that if the Graetz number of the flow is between 1 and 10, small variations in the flow rate result in large differences in blood temperature drop. Single separate blood vessels of the right Graetz number may have substantial thermoregulatory capabilities.
