The Role of Physiology in Health and Disease

Abstract

Star Saukanj*

Physiology is the branch of biology that studies the functions and mechanisms occurring within living organisms. It focuses on how biological systems work at molecular, cellular, tissue and organ levels to maintain life. By examining the normal functioning of the body, physiology also provides invaluable insights into how these functions can be disrupted, leading to disease. In both health and disease, understanding physiology is crucial as it informs medical practice, disease prevention, and therapeutic strategies. The body’s physiological processes are essential for maintaining homeostasis, which is the stable internal environment necessary for proper functioning. Homeostasis regulates factors such as body temperature, pH, blood pressure, and glucose levels. When these processes become unbalanced or disrupted, the body is prone to disease.
