Darwinists have repeatedly used the terms “constrained” and “failing” physiology to describe our heart and blood vessels. After all, the leading cause of death in the United States is cardiovascular disease, which includes heart disease, stroke, and atherosclerosis. Therefore, by Darwinian reasoning, the anatomical and physiological design of the circulatory system must be bad, and evolution in its randomness has given us a “raw” deal. This position is stated by Nesse and Williams (1995, p. 5), “Bones, physiology, the nervous system — the body has thousands of consummate designs that elicit our wonder and admiration. By contrast, however, many aspects of the body seem amazingly crude” [like blood vessels]… “An intricate network of arteries carries just the right amount of blood to every part of the body. Yet many of us develop cholesterol deposits on the walls of our arteries, and the resulting blockage in blood flow (atherosclerosis) causes heart attacks and strokes. It is as if a Mercedes-Benz designer specified a plastic soda straw for the fuel line!” In this paper, we examine the Darwinists’ repeated criticism of the circulatory system’s functional design. A case for the exquisite design of the circulatory system in general, and the coronary vessels in particular, is made by discussing its flexibility in adjusting blood pressure, and in providing alternate routes of blood flow if blockage or impairment of a vessel occurs.
