Detailed explanation-1: -Homeostasis is generally maintained by a negative feedback loop that includes a stimulus, sensor, control centre, and effector . Negative feedback serves to reduce an excessive response and to keep a variable within the normal range. Negative feedback loops control body temperature and the blood glucose level.

Detailed explanation-2: -To control homeostasis, the brain talks to the body with the help of chemical messengers called hormones. Hormones travel through the blood stream from the brain to the body and back.

Detailed explanation-3: -Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high; glucagon raises blood glucose when levels are low)
