Verified step by step guidance

Understand the concept of negative feedback mechanisms: Negative feedback is a process that counteracts a change in a physiological variable to maintain homeostasis.

Identify the role of the endocrine system: The endocrine system is responsible for releasing hormones into the bloodstream to regulate various body functions, including metabolism and blood sugar levels.

Recognize the hormones involved in blood sugar regulation: Insulin and glucagon are the primary hormones that regulate blood glucose levels, both of which are secreted by the pancreas, an endocrine gland.

Explain how insulin and glucagon work: When blood sugar levels rise, insulin is released to help cells absorb glucose, lowering blood sugar. Conversely, when blood sugar levels drop, glucagon is released to stimulate the release of glucose into the blood.

Conclude that blood sugar regulation is a function of the endocrine system: Since the regulation of blood glucose involves hormone secretion and feedback mechanisms, it is primarily controlled by the endocrine system.
