Abstract
1. A heat transfer model was used to examine the possible sites for the cardiovascular control of heat exchange in ectothermic reptiles. 2. Predicted effects of changes in blood flow on heating and cooling remained constant or increased with mass. 3. Predicted sites at which changes in blood flow strongly affect heating and cooling rates differed between small (⩽1 kg) and large (⩾10 kg) reptiles. 4. In small reptiles (⩽1 kg) blood flow to appendages affected heating and cooling rates but blood flow to the torso had little effect on heat exchange. 5. In large animals (⩾10 kg) changing blood flow to either appendages or torso affected heat exchange; small changes in cardiac output have maximum effects when they occur at the appendages, but larger changes in cardiac output can achieve even larger effects by changing torso blood flow.
