What is the Meaning of Human Physiology?

Human physiology is the scientific discipline dedicated to the study of the mechanical, physical, and biochemical functions of living human organisms, their organs, and the cells of which they are composed. This field explores how the body maintains homeostasis, the dynamic equilibrium necessary for survival, by coordinating complex processes like respiration, circulation, metabolism, and hormonal signaling. A deep understanding of physiology provides the fundamental framework for all clinical practice and health optimization strategies.

What is the Origin of Human Physiology?

The term "physiology" originates from the ancient Greek physiologia, meaning "knowledge of nature," with physis meaning nature or origin, and logia meaning study. As a distinct scientific discipline, it emerged during the Enlightenment and became formalized in the 19th century with the application of experimental methods to understand bodily functions. It serves as the bridge between anatomy and clinical medicine.

What is the Mechanism of Human Physiology?

The mechanism of human physiology is the collective operation of interconnected organ systems, each contributing to the maintenance of the internal environment through regulatory feedback loops. For example, the endocrine system releases hormones to regulate metabolism and growth, while the nervous system provides rapid, electrochemical coordination. These systems constantly adjust variables like blood glucose, $mathrm{pH}$, and body temperature, ensuring cellular function remains within the narrow, viable range required for health and longevity.
