GlossaryHomeostasis

process of maintaining stable internal conditions in organisms

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions. This involves various physiological mechanisms that regulate factors like temperature, pH, and electrolyte balance to ensure optimal functioning of cells and organs. For example, the human body sweats to cool down when it's hot, helping to keep the internal temperature within a narrow, healthy range.
