This hormone from the pancreas causes cells to take up glucose from the bloodstream.

• Insulin
• Glucagon
• Cortisol
• Epinephrine

Calcitonin is a hormone that lowers blood calcium levels by causing calcium uptake in bones. Parathyroid hormone raises blood calcium levels by causing bones to release calcium into the bloodstream. Based on your understanding of hormones, homeostasis, and feedback loops, which hormone will be released if blood calcium levels are low?

• Calcitonin
• Parathryoid hormone
• Glucagon
• Insulin
