After studying this chapter, you will be able to: • Distinguish between anatomy and physiology, and identify several branches of each • Describe the structure of the body, from simplest to most complex, in terms of the six levels of organization • Identify the functional characteristics of human life • Identify the four requirements for human survival • Define homeostasis and explain its importance to normal human functioning • Use appropriate anatomical terminology to identify key body structures, body regions, and directions in the body • Compare and contrast at least four medical imaging techniques in terms of their function and use in medicine Though you may approach a course in anatomy and physiology strictly as a requirement for your field of study, the knowledge you gain in this course will serve you well in many aspects of your life. An understanding of anatomy and physiology is not only fundamental to any career in the health professions, but it can also benefit your own health. Familiarity with the human body can help you make healthful choices and prompt you to take appropriate action when signs of illness arise. Your knowledge in this field will help you understand news about nutrition, medications, medical devices, and procedures and help you understand genetic or infectious diseases. At some point, everyone will have a problem with some aspect of their body and your knowledge can help you to be a better parent, spouse, partner, friend, colleague, or caregiver...

Learning Objectives By the end of this section, you will be able to: • Compare and contrast the study of anatomy and physiology • Discuss the fundamental structure-function relationship between anatomy and physiology Human anatomy is the scientific study of the body’s structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope, while other, larger structures can readily be seen, manipulated, measured, and weighed. The word “anatomy” comes from the Greek root “ana” which means “to cut apart” and “tomia” which means “to cut.” Human anatomy was first studied by observing the exterior of the body, wounds of soldiers, and other injuries. Later, physicians were allowed to dissect bodies of the dead to augment their knowledge. When a body is dissected, its structures are cut apart in order to observe their physical attributes and their relationships to one another. Dissection is still used in medical schools, anatomy courses, and in pathology labs. In order to observe structures in living people, however, a number of imaging techniques have been developed. These techniques allow clinicians to visualize structures inside the living body such as a cancerous tumor or a fractured bone. Like most scientific disciplines, anatomy has areas of specialization. Gross anatomy is the study of the larger structures of the body, those visible without the aid of magnification (image below, a). Gross and macro both mean “large,” t...

Physiology Has Latin Roots The Latin root physio- generally means "physical", so human physiology deals with just about everything that keeps us alive and working, and other physiology specialties do the same for other animals and for plants. To do anything serious in the field of health, you've obviously got to know how the body's organs and cells function normally. Physiology used to be considered separately from anatomy, which focuses on the body's structures; however, it's now known that structure and function can't easily be separated in a scientific way, so "anatomy and physiology" are often spoken of in the same breath. Recent Examples on the Web The ambitious study began as a sketch on the back of a cocktail napkin at a hotel bar where Sessa, then a professor of plant systematics at the University of Florida, and Jarmila Pittermann, a professor of plant physiology at UC Santa Cruz, were debriefing after a conference. — Corinne Purtill, Los Angeles Times, 31 May 2023 Reach Bryant Stamford, a professor of kinesiology and integrative physiology at Hanover College, at [email protected]. — Bryant Stamford, The Courier-Journal, 11 May 2023 In his worlds, familiar physiology is bent into strange new shapes, showing us that the seeming fixity of our bodies is only a soothing illusion. — Alexandra Kleeman, New York Times, 21 Apr. 2023 Human physiology assures that some babies will always be born early, and many would die without neonatal intensive care at birth. — Rachel...

Physiology Definition Physiology is the study of all the physical and chemical processes that take place in organisms in order for them to perform all the functions and activities associated with living. Physiology can be studied at the molecular level all the way up to the level of entire organisms, and includes everything in between like cells, tissues, organs, and body systems. It involves studying how the different parts of the body work, separately and together, to allow an organism to function properly. History of Physiology The modern-day field of physiology has its roots in ancient cultures such as those of India, Egypt, and Greece. The Ancient Greek philosopher Hippocrates believed that the body contained four important fluids called the “four humors”: phlegm, blood, yellow bile, and black bile. He believed that if there was any disturbance in the amounts of these fluids in the body and their ratios to each other, a person would suffer from ill health. For example, too much yellow bile was thought to cause anger, irritability, and jealousy, while too much black bile was associated with being depressed, pessimistic, and withdrawn. These ideas were used in medicine from around 420 B.C. all the way until the 1800s. In 1838, there was a paradigm shift when Matthias Schleiden and Theodor Schwann developed cell theory, which hypothesized that the body was made up of billions of individual cells. This theory was developed through the use of the compound microscope, a too...

Physiology is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together. It helps us understand what happens in a healthy body in everyday life and what goes wrong when someone gets sick. Most of physiology depends on basic research studies carried out in a laboratory. Some physiologists study single proteins or cells, while others might do research on how cells interact to form tissues, organs, and systems within the body. Physiology vs. Anatomy While human anatomy is the study of the body’s structures, physiology is the study of how those structures work. An imaging scan like an X-ray or What Physiology Tells Us About the Body Doctors use physiology to learn more about many different organ systems, including: • The cardiovascular system -- your • The • The • The • The muscular system -- the muscles you use to move your body • The • The renal system -- your • The reproductive system -- • The • The skeletal system -- bones, joints, cartilage, and connective tissue For each system, physiology sheds light on the chemistry and physics of the structures involved. For example, physiologists have studied the electrical activity of cells in the Physiology revolves around understanding how the human body maintains a steady state while adapting to outside conditions, a process called homeostasis. How do your organ systems keep your temperature relatively stable...
