This book comprehensively addresses the physics and engineering aspects of human physiology by using and building on first-year college physics and mathematics. Topics include the mechanics of the static body and the body in motion, the mechanical properties of the body, muscles in the body, the energetics of body metabolism, fluid flow in the cardiovascular and respiratory systems, the acoustics of sound waves in speaking and hearing, vision and the optics of the eye, the electrical properties of the body, and the basic engineering principles of feedback and control in regulating all aspects of function. The goal of this text is to clearly explain the physics issues concerning the human body, in part by developing and then using simple and subsequently more refined models of the macrophysics of the human body. Many chapters include a brief review of the underlying physics. There are problems at the end of each chapter; solutions to selected problems are also provided. This second edition enhances the treatments of the physics of motion, sports, and diseases and disorders, and integrates discussions of these topics as they appear throughout the book. Also, it briefly addresses physical measurements of and in the body, and offers a broader selection of problems, which, as in the first edition, are geared to a range of student levels. This text is geared to undergraduates interested in physics, medical applications of physics, quantitative physiology, medicine, and biomedical engineering.
Blood pumping through our veins is a vital example of Poiseuille flow; the act of running requires friction to propel the runner forward; and the quality of our eyesight demonstrates how properties of light enable us to correct near- and far-sightedness. --
Biomechanics of the Human Body teaches basic physics concepts using examples and problems based on the human body. The reader will also learn how the laws of mechanics may help to understand the conditions of the static and dynamic equilibrium of one of the marvels of nature: the human body. The mathematical language used in physics has always been pointed out as responsible for students’ difficulties. So, each concept given is followed by explanatory examples, with subsequent application and fixation exercises. It is a richly illustrated book that facilitates the comprehension of presented concepts. Biomechanics of the Human Body can be useful to students of physical and occupational therapy, physical education, the life sciences, and health care professionals who deal with biomechanics. This book is also recommended for sport practitioners as well as the general reader interested in the mechanics of the human body.
"Body Physics was designed to meet the objectives of a one-term high school or freshman level course in physical science, typically designed to provide non-science majors and undeclared students with exposure to the most basic principles in physics while fulfilling a science-with-lab core requirement. The content level is aimed at students taking their first college science course, whether or not they are planning to major in science. However, with minor supplementation by other resources, such as OpenStax College Physics, this textbook could easily be used as the primary resource in 200-level introductory courses. Chapters that may be more appropriate for physics courses than for general science courses are noted with an asterisk symbol (*). Of course this textbook could be used to supplement other primary resources in any physics course covering mechanics and thermodynamics"--Textbook Web page.
This unique introduction to physics for readers who are particularly interested in the human body covers a limited number of distinct physics topics (related to mechanics and heat) in great depth and with many examples and problems that relate directly to readers' interests. Each topic is developed quantitatively using high school-level algebra (linear equations, simultaneous equations), trigonometric functions, and vectors. Applications focus on typical situations--e.g., the need for and proper use of a cane; the need for heat transfer from the body to the environment during exercise and the relative contributions of the various mechanisms (convection, radiation, evaporation of sweat); the relation between energy ingested as food and energy expended during exercise; etc. Motion; Force; Vectors; Newton's Second Law; Momentum And Impulse; Angular Motion; Torque; Shoulder; Knee; Lower Back; FHP; Heat And Energy; Conservation Of Energy; Work; Chemical Energy; Elastic Energy; Nuclear Energy. For premedical students, Physical Therapists, and Occupational Therapists.

Physiognomy and ekphrasis are two of the most important modes of description in antiquity and represent the necessary precursors of scientific description. The primary way of divining the characteristics and fate of an individual, whether inborn or acquired, was to observe the patient’s external characteristics and behaviour. This volume focuses initially on two types of descriptive literature in Mesopotamia: physiognomic omens and what we might call ekphrastic description. These modalities are traced through ancient India, Ugaritic and the Hebrew Bible, before arriving at the physiognomic features of famous historical figures such as Themistocles, Socrates or Augustus in the Graeco-Roman world, where physiognomic discussions become intertwined with typological analyses of human characters. The Arabic compendial culture absorbed and remade these different physiognomic and ekphrastic traditions, incorporating both Mesopotamian links between physiognomy and medicine and the interest in characterological ‘types’ that had emerged in the Hellenistic period. This volume offer the first wide-ranging picture of these modalities of description in antiquity.
Why do we walk on two legs? How do our muscles know how to work together when we dance? How does our brain work with our hands to sink a basketball? In Human Movement: How the Body Walks, Runs, Jumps, and Kicks, readers ages 12 to 15 learn the basic anatomy and physiology of the human body and discover how bones, muscles, tendons, and nerves work together to make movement possible. Bones give the body structure and the ability to stay upright. Muscles make possible the movement of the bones. The brain tells the muscles what to do and when to do it. And your heart, lungs, and other organs provide the fuel that powers movement. Human Movement takes a look at all of the components of the human body and examines how they allow you to move and interact with the world around you. Readers also learn what they can do to keep their bodies healthy and fit and moving well. Combining hands-on activities with biology, chemistry, biomechanics, and nutrition, Human Movement offers entertaining graphic novel illustrations and fascinating sidebars to illuminate the topic and engage readers further. Human Movement integrates a digital learning component by providing links to primary sources, videos, and other relevant websites to deepen readers’ experiences and strengthen practical connections to the material. Projects include building a hand model with working muscles and tendons, testing what makes bones strong, examining how changing your center of gravity affects balance and motion, identifying how different types of joints work, and using yeast to investigate how the body metabolizes food into energy. Additional materials include a glossary, and a list of current reference works, websites, and Internet resources.
Alberto Rios explains the world not through reason but magic. These poems-set in a town that straddles Mexico and Arizona-are lyric adventures, crossing two and three boundaries as easily as one, between cultures, between languages, between senses. Drawing upon fable, parable, and family legend, Rios utilizes the intense and supple imagination of childhood to find and preserve history beyond facts: plastic lemons turning into baseballs, a grandmother's long hair reaching up to save her life, the painted faith jumpers leaping to the earth and crowd below. This is magical realism at its shimmering best. The smallest muscle in the human body is in the ear. It is also the only muscle that does not have blood vessels; It has fluid instead. The reason for this is clear: The ear is so sensitive that the body, if it heard its own pulse, Would be devastated by the amplification of its own sound. In this knowledge I sense a great metaphor, But I do not want to be hasty in trying to capture or describe it. Words are our weakest hold on the world. -from "Some Extensions of the Sovereignty of Science" "Rios is onto something new in his poetry-in the way that the real poets of any time always are."-American Book Review Alberto Rios teaches at Arizona State and is the author of eight books of poetry, three collections of short stories, and a memoir about growing up on the Mexican border. He is the recipient of numerous awards and his work is included in over 175 national and international literary anthologies. His work is regularly taught and translated, and has been adapted to dance and both classical and popular music.
