...Clinical Notes The Visible Human Project p. 7 Homeostasis and Disease p. 13 An Introduction to Studying the Human Body This textbook will serve as an introduction to the inner workings of your body, providing information about both its structure and its function. Many of the students who use this book are preparing for careers in health-related fields—but regardless of your career choice, you will find the information within these pages relevant to your future. You do, after all, live in a human body! Being human, you most likely have a seemingly insatiable curiosity—and few subjects arouse so much curiosity as our own bodies. The study of anatomy and physiology will provide answers to many questions regarding the functioning of your body in both health and disease. Although we will be focusing on the human body, the principles we will learn apply to other living things as well. Our world contains an enormous diversity of living organisms that vary widely in appearance and lifestyle. One aim of biology—the science of life—is to discover the unity and the patterns that underlie this diversity, and thereby shed light on what we have in common with other living things. Animals can be classified according to their shared characteristics, and birds, fish, and humans are members of a group called the vertebrates, characterized by a segmented vertebral column. The shared characteristics and organizational patterns provide useful clues about how these animals have evolved over time...

...in the human body. Physiology depends on anatomy; anatomy is study of the structures in the body, physiology is the study of the functions of those structures. In other words, without structure there is no function. Physiology depends on anatomy, the operation or function of a structure is dictated by its anatomy. Anatomy and physiology are really inseparable because function always reflects structure. For example, oxygen and carbon dioxide are exchanged across the thin membranes of the lungs but not across the skin. (Marieb and Hoehn, 2010, page 3) 2. Describe the three patterns of chemical reactions. Synthesis reaction is when atoms or molecules combine to form a larger, more complex molecule. It always involves bond formation and can be represented as A+B→AB. This is the basis of constructive activities in body cells. Amino acids are joined together to form a protein molecule. Decomposition reaction occurs when a molecule is broken down into smaller molecules. It can be represented as AB→A+B. Decomposition reactions are the reverse of synthesis reactions. This underlies all degradative processes in body cells. Bonds are broken in larger molecules, resulting in smaller, less complex molecules. Glycogen is broken down to release glucose units. Exchange reactions involve both synthesis and decomposition. Bonds are both made and broken, which is also called displacement reactions. During the exchange reaction, parts of the reactant molecules change patterns producing...

...Advance concept of nursing I Unit 1 Nursing process The nursing process is an organized sequence of problem solving steps used to identify and to manage the health problems of clients .The nursing process is the framework for nursing care in all health care settings.When nursing practice follows the nursing process, clients receive quality care in minimal time with maximal efficiency. The steps of nursing process 1)Assesment 2)Diagnosis 3)Planning 4)Implementation 5)Evaluation Assessment An RN uses a systematic, dynamic way to collect and analyze data about a client, the first step in delivering nursing care. Assessment includes not only physiological data, but also psychological, sociocultural, spiritual, economic, and life-style factors as well. For example, a nurse’s assessment of a hospitalized patient in pain includes not only the physical causes and manifestations of pain, but the patient’s response—an inability to get out of bed, refusal to eat, withdrawal from family members, anger directed at hospital staff, fear, or request for more pain mediation. Diagnosis The nursing diagnosis is the nurse’s clinical judgment about the client’s response to actual or potential health conditions or needs. The diagnosis reflects not only that the patient is in pain, but that the pain has caused other problems such as anxiety, poor nutrition, and conflict within the family, or has the potential to cause complications—for example, respiratory infection is a potential hazard...

...teens worldwide. The pressure for being thin and looking good is everywhere around us: from magazine models to movies stars, the subliminal message is always present and has a great impact on the youth’s lives nowadays. The world’s pressure on these young people can become extremely dangerous when the obsession with their bodies gets out of control. Anorexia Nervosa is one of the most common life-threatening eating disorders among young people and is defined by a refusal to maintain minimal body weight within 15 percent of an individual's normal weight through self-starvation (http://www.nami.org/Template.cfm?Section=By_Illness&template=/ContentManagement/ContentDisplay.cfm&ContentID=102975/ Nami, 2010, para.1). Anorexia Nervosa may lead to serious health problems and potential death. Fortunately, with help from professionals, therapy, family & friends, this serious eating disorder can be treated and cured, and the patient can return to live a healthy and normal life. Who does it Anorexia Nervosa affect and why? Eating disorders are found nearly exclusively in Western or Westernized populations, and mainly affect women between 16 and 19 years old, in secondary schools, colleges and campuses (Giordano, 2005, p.19-20). Our culture has changed a lot over the decades. In the past, being too thin was synonym of malnutrition and/or poverty. Slim women were considered ugly and unattractive. However, society values have changed. Nowadays...

...Chapter 1 Introduction to Pathophysiology Lee-Ellen C. Copstead Key Questions • What is pathophysiology? • How are etiology and pathogenesis used to predict clinical manifestations and response to therapy? • How are normal and abnormal physiologic parameters defined? • What general factors affect the expression of disease in a particular person? • What kinds of information about disease can be gained through understanding concepts of epidemiology? http://evolve.elsevier.com/Copstead/ • Review Questions and Answers • Glossary (with audio pronunciations for selected terms) • Animations • Case Studies • Key Points Review Pathophysiology derives from the intersection of two older, related disciplines: pathology (from pathos, suffering) and physiology (from physis, nature). Pathology is the study and diagnosis of disease through examination of organs, tissues, cells, and bodily fluids. Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Together, as pathophysiology, the term refers to the study of abnormalities in physiologic functioning of living beings. Pathophysiology seeks to reveal physiologic responses of an organism to disruptions in its internal or external environment. Because humans exhibit considerable diversity, healthy structure and function are not precisely the same in any two individuals. However, discovering the common and expected responses to abnormalities in physiologic functioning is useful, and it...

...and patterns of health-events, health- characteristics and their causes or influences in well-defined populations. It is the cornerstone method of public health research, and helps inform policy decisions and evidence-based by identifying risk factors for disease and targets for preventive medicine. Epidemiologists are involved in the design of studies, collection and statistical analysis of data, and interpretation and dissemination of results (including peer review and occasional systematic review).Major areas of epidemiological study include outbreak investigation, disease surveillance and biomonitoring, and comparisons of treatment effects such as in clinical trials. Epidemiologists rely on a number of other scientific disciplines such as biology (to better understand disease processes), biostatistics (to make efficient use of the data and draw appropriate conclusions), and exposure assessment and social science disciplines (to better understand proximate and distal risk factors, and their measurement). I would like to discuss elderly patients as my vulnerable population. There is no set age at which a person maybe under the care of a geriatric physician. The physician aims to promote health by preventing disease and disabilities in geriatric adults. A gerontologist specializes in the aging process. Adult medicine differs from the geriatric patient because the focus is on the elderly patient. The decline in physiological reserve in organs makes...

...1980s. Healthcare costs in the United States have risen dramatically during the past 40 years, due in part to longer average life spans, which give rise to greater costs because older citizens require greater care, and the employment of technologies that extend the life of patients, which generally results in greater spending. Insurance costs have likewise increased dramatically, and a relatively large percentage of U.S. citizens and other residents are uninsured or underinsured. According to information from the census bureau in 2001, 41.2 million Americans, constituting 14.2 percent of the population, did not have Health Insurance. The healthcare system is largely controlled by the free market, which is believed to provide limitations on how much physicians and other specialists can charge to their patients. However, many critics of the current system, including organizations composed of physicians, note that the system has become largely bureaucratic and that cost-cutting measures and pressures caused by competition and the need for profit have reduced the effectiveness of medical practice. Despite these problems, many commentators have not been able to agree as to the proper level of control that state or federal governments should have over health care. Following World War II, the number of Americans that had private insurance policies grew dramatically. In 1965, Congress approved the development of Medicare and Medicaid to assist the elderly and the poor in being able to...
