REGULATION OF INTERNAL ENVIRONMENT (HOMEOSTASIS) 2

Regulation of the Internal Environment (Homeostasis) refers to the biological processes by which living organisms maintain stable internal conditions despite external environmental changes. This balance is essential for proper functioning and survival. Key parameters regulated through homeostasis include body temperature, pH levels, glucose concentration, and water balance. Mechanisms such as feedback loops play a central role; for instance, negative feedback systems help restore balance by counteracting deviations, like the regulation of blood sugar levels through insulin and glucagon. Organs such as the kidneys, liver, and brain, alongside the endocrine and nervous systems, coordinate to maintain this equilibrium. Homeostasis ensures that cells operate optimally, supporting overall health and adaptability.
