Which body system is used to regulate blood sugar through hormone response?

• A. Nervous
• B. Digestive
• C. Endocrine
• D. Circulatory

Answer: (C)

Blood sugar is regulated by hormones traveling through the bloodstream, a function of the endocrine system. The pancreas releases insulin to lower blood glucose when levels are high and glucagon to raise it when they’re low, creating a feedback loop that keeps glucose in a narrow range after meals and during fasting. The nervous system can influence glucose metabolism indirectly through stress responses, but the direct hormonal regulation comes from the endocrine system. The digestive system isn’t the primary regulator, and while the circulatory system transports these hormones, it doesn’t regulate glucose by itself.
