The Human Body Life Science

There are more than six billion humans who all share the same basic structure. Scientists categorize body parts by function. There are many systems such as the cardiovascular system, the respiratory system, the digestive system, the urinary system, and the endocrine system. The body is an amazing machine, and these are just a few of the parts!

Uses a question and answer format to discuss the anatomy and function of the human body.

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.

Tells the story of human development from egg to adult, showing how the understanding of how human beings come to be has been transformed in recent years.

Most of us take our body for granted and are never aware of its amazing capabilities. This book looks at how the seven octillion atoms that make up the human body are grouped into organs, tissues, nerves, fibres, fluids and more in such a way that the entire system runs smoothly without us ever knowing about it. It explains the hidden world of hormones and enzymes, the battleground of your immune system, the senses and much more. It also reveals the astonishing secrets of the human body, from the 15 'other senses' we have beyond the known five, to the reason we have eyes capable of seeing the Andromeda galaxy 2.5 million light years away. Chapters include: Cells, tissues and body structure The skin, skeleton and muscles The cardiovascular system Internal protectors: warriors behind the scenes The respiratory system

Taking a broad, integrated view of the field, The Human Body spans human physiology and anatomy, histology, cell biology, pharmacology, and genetics and immunology, to give a complete overview that forms the perfect foundation to any biomedical or healthcare science course.

In this landmark book of popular science, Daniel E. Lieberman—chair of the department of human evolutionary biology at Harvard University and a leader in the field—gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease. The Story of the Human Body brilliantly illuminates as never before the major transformations that contributed key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering, leading to our superlative endurance athleticism; the development of a very large brain; and the incipience of cultural proficiencies. Lieberman also elucidates how cultural evolution differs from biological evolution, and how our bodies were further transformed during the Agricultural and Industrial Revolutions. While these ongoing changes have brought about many benefits, they have also created conditions to which our bodies are not entirely adapted, Lieberman argues, resulting in the growing incidence of obesity and new but avoidable diseases, such as type 2 diabetes. Lieberman proposes that many of these chronic illnesses persist and in some cases are intensifying because of “dysevolution,” a pernicious dynamic whereby only the symptoms rather than the causes of these maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes even compel us to create a more salubrious environment.
