Feedback mechanisms that regulate sugar levels in the blood using the hormone Insulin belong to which system?
A
Nervous System
B
Immune System
C
Digestive System
D
Endocrine System
Explanation: 

Detailed explanation-1: -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-2: -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-3: -Through its various hormones, particularly glucagon and insulin, the pancreas maintains blood glucose levels within a very narrow range of 4–6 mM. This preservation is accomplished by the opposing and balanced actions of glucagon and insulin, referred to as glucose homeostasis.
