What is the definition of physiology?

Physiology is defined as the study of human body function. It focuses on how organs, systems, tissues, and cells work together to maintain life and health. This includes understanding processes such as metabolism, respiration, circulation, and growth, as well as how the body responds to various stimuli and conditions.

This distinction is essential in the field of health and fitness, as a solid grasp of physiological concepts helps trainers and health professionals design effective exercise programs, understand the body's adaptations to training, and address client needs comprehensively. By knowing how the body functions, professionals can optimize training outcomes and promote overall wellness.
