It’s been five hours since you had your last meal, which has made your blood-glucose level drop. How is your endocrine system helping to maintain this level?

a.) The pituitary gland produces antidiuretic hormone (ADH), which stimulates the kidneys to break down glycogen into glucose and release it into the blood.

b.) The thyroid gland produces thyroxine, which stimulates the metabolic rate so that more glycogen is broken into glucose and released in the blood.

c.) The pancreas produces glucagon, which stimulates the liver to break down glycogen into glucose and release it into the blood.
