body temperature
B
blood sugar
C

D
heart rate

Detailed explanation-1: -The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

Detailed explanation-2: -Regulating Temperature A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms.

Detailed explanation-3: -Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state.

Detailed explanation-4: -Hormones of the Pancreas. Regulation of blood glucose is largely done through the endocrine hormones of the pancreas, a beautiful balance of hormones achieved through a negative feedback loop. The main hormones of the pancreas that affect blood glucose include insulin, glucagon, somatostatin, and amylin.

Detailed explanation-5: -The pancreas has key roles in maintaining normal blood glucose levels by producing and releasing insulin and glucagon.
