The Principles of Physiology

The principles of physiology describe how the body functions to maintain health and stability, called homeostasis. It involves understanding how organs and systems work together—such as the heart pumping blood, lungs exchanging gases, nerves transmitting signals, and muscles enabling movement. These processes are coordinated through complex feedback mechanisms to adapt to changes like exercise or injury. Essentially, physiology explains the dynamic balance and interactions that keep our bodies running smoothly, allowing us to think, move, breathe, and heal efficiently.
