What is physiology?


Physiology covers a multitude of disciplines within human biology and beyond.
The study of physiology is, in a sense, the study of life. It asks questions about the internal workings of organisms and how they interact with the world around them. Physiology tests how organs and systems within the body work, how they speak to each other, and how they combine their efforts to make conditions favorable for survival. Human physiology, specifically, is often separated into subcategories, these disciplines have an impressive breadth of scope. Researchers in the field can focus on anything from microscopic organelles in cell physiology up to more cumbersome topics, such as ecophysiology, which looks at whole organisms and how they adapt to environments. The most relevant arm of physiological research to Medical News Today is applied human physiology; this field investigates biological systems at the level of the cell, organ, system, anatomy, organism, and everywhere in between. In this article, we will visit some of the subsections of physiology, developing a brief overview of the huge subject that is physiology. Firstly, though, a highly abbreviated history of physiology.
