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...

Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Some specializations within each of these sciences follow: • Gross (macroscopic) anatomy is the study of body parts visible to the naked eye, such as the heart or bones. • Histology is the study of tissues at the microscopic level. • Cytology is the study of cells at the microscopic level. • Neurophysiolog...

Anatomy learning resources: Choosing the right one You may have already spent some time looking at different anatomy learning resources and found yourself feeling overwhelmed by the sheer number of options. Indeed, deciding on the resource(s) you’ll use to learn can be more stressful than learning itself! In this section, we’re going to walk you through the most common anatomy learning resources, as well as the pros and cons of each. Hopefully this will make it easier for you to decide on the right one for you and your needs. University lectures, seminars and labs Of course, if you’re studying anatomy as part of your school or university course, there’s not much getting away from lectures, seminars and laboratories. For those of you to whom this applies, these resources will likely provide the foundation for your anatomy studies. Unfortunately, for most students faced with the task of learning copious amounts of anatomy, these resources are not sufficient alone.It can be difficult to understand the different structures and connections between them when viewing a cadaver. And in some cases, professors will only cover certain topics, leaving the onus on you to go and learn everything else in your spare time. In other cases, you might not understand or connect with a particular Dissections in the 21st century: Antiquated or useful for learning anatomy?
