The most common examples of homeostasis in the human body include temperature regulation, acid-base balance, regulation of glucose concentration and. Two general mechanisms are involved in homeostatic regulation: autoregulation and extrinsic regulation: autoregulation. Homeostasis: homeostasis, any self-regulating process by which biological systems tend to maintain stability.
