The Human Physiology

Human physiology is the study of how the body's systems function to maintain life. It explains how organs like the heart pump blood, the lungs supply oxygen, muscles enable movement, and the brain controls everything. The body has complex networks, like the nervous and circulatory systems, that work together to keep things balanced—regulating temperature, processing nutrients, removing waste, and defending against illness. Understanding physiology helps us grasp how our bodies operate normally and how they respond to health issues, guiding medical treatment and promoting overall well-being.
