D
Skeletal system
Verified step by step guidance
1
Understand the role of blood sugar regulation in the body. Blood sugar levels are primarily controlled by hormones, which are chemical messengers that regulate various physiological processes.
Identify the system responsible for producing and releasing hormones. The endocrine system is the system in the body that produces hormones, including insulin and glucagon, which directly regulate blood sugar levels.
Learn how insulin and glucagon function. Insulin lowers blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the release of glucose from stored glycogen in the liver.
Compare the functions of the other systems listed in the question. The integumentary system (skin, hair, nails) protects the body, the respiratory system facilitates gas exchange, and the skeletal system provides structural support. None of these systems directly regulate blood sugar levels.
Conclude that the endocrine system is the correct answer because it most directly affects blood sugar levels through the action of hormones like insulin and glucagon.
