physiological mechanisms

Physiological mechanisms are the body’s natural processes that keep us alive and functioning. They include functions like breathing, which brings oxygen into the lungs; circulation, which delivers oxygen and nutrients through the blood; and nerve signals that control movement and responses. Hormones act as messengers to regulate growth, metabolism, and mood. The immune system defends against infections, while the kidneys and liver filter waste. Together, these processes work seamlessly to maintain balance, respond to changes, and help us stay healthy. Understanding these mechanisms helps us appreciate how our bodies adapt and stay functional.
