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: -Why are negative feedback loops used to control body homeostasis? An adjustment to a change in the internal or external environment requires a change in the direction of the stimulus. A negative feedback loop accomplishes this, while a positive feedback loop would continue the stimulus and result in harm to the animal.
Detailed explanation-3: -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.
