Most of us think about our circulatory system only when something goes wrong, but the amazing story of how it goes right--"magnificently right," as author Steven Vogel puts it--is equally worthy of our attention.

It is physically remarkable, bringing food to (and removing waste from) a hundred trillion cells, coursing through 60,000 miles of arteries and veins (equivalent to over twice around the earth at the equator). And it is also intriguing. For instance, blood leaving the heart flows rapidly through the arteries, then slows down dramatically in the capillaries (to a speed of one mile every fifty days), but in the veins, on its way back to the heart, it speed up again. How?
In Vital Circuits, Steven Vogel answers hundreds of such questions, in a fascinating, often witty, and highly original guide to the heart, vessels and blood. Vogel takes us through the realm of biology and into the neighboring fields of physics, fluid mechanics, and chemistry. We relive the discoveries of such scientists as William Harvey and Otto Loewi, and we consider the circulatory systems of such fellow earth-dwellers as octopuses, hummingbirds, sea gulls, alligators, snails, snakes, and giraffes. Vogel is a master at using everyday points of reference to illustrate potentially daunting concepts. Heating systems, kitchen basters, cocktail parties, balloons--all are pressed into service. And we learn not only such practical information as why it's a bad idea to hold your breath when you strain and why you might want to wear support hose on a long airplane flight, but also the answers to such seemingly unrelated issues as why duck breasts (but not chicken breasts) have dark meat and why dust accumulates on the blades of a fan.
But the real fascination of Vital Circuits lies neither in its practical advice nor in its trivia. Rather, it is in the detailed picture we construct, piece by piece, of our extraordinary circulatory system. What's more, the author communicates not just information, but the excitement of discovering information. In doing so, he reveals himself to be an eloquent advocate for the cause of science as the most interesting of the humanities. Anyone curious about the workings of the body, whether afflicted with heart trouble or addicted to science watching, will find this book a goldmine of information and delight.

Steven Vogel is James B. Duke Professor, Emeritus, in the Department of Biology at Duke University.

As it has turned out, my activities as a teacher and writer have extended well beyond the explication of the immediate results of research. The first two of my seven books, A Functional Bestiary: Laboratory Studies about Living Systems and A Model Menagerie: Laboratory Studies about Living Systems, provide eclectic material for teaching laboratories in introductory biology. The third, Life in Moving Fluids, finds most use as an entry point into fluid mechanics; it is now in its second (much enlarged) edition. The fourth, Life's Devices, takes comparative biomechanics as a paradigm for thinking about science, using the very mundanity of the subject to draw in non-scientists rather than presenting them with some system of revelation. The book was generated through a course given to adults in a non-specialist master's program and is now in use in a variety of undergraduate courses; it was selected by a science-oriented book club and has won a substantial award. Material in that book reappears in expanded and more sophisticated form in my recent undergraduate textbook, Comparative Biomechanics. The fifth, Vital Circuits, is of a deliberately less pedagogical character; it's about circulatory systems, whose disabilities are of widespread interest. But it uses them as a vehicle to talk in biological rather than pathological terms and to illustrate how a such a subject is viewed by a biological scientist in contrast to a journalist or a physician. Cats' Paws and Catapults, also aimed at the general reader, compares the mechanical technologies of nature with that of humans. Prime Mover, another trade book, tries to link the biomechanics and physiology of muscle to the role it has played in human activities. Finally, I've written for more popular publications, such as Natural History and Discover, attempting to create pieces that explain science rather than merely reporting on the current activities of scientists, and I've become involved with several science museums, again in activities aimed at explaining science as part of contemporary culture. Two additional books, both aimed at a general scientific readership, are currently in gestation.(less)
