Question 1

What is the relationship between insulin and glucagon in homestasis?

Accepted Answer

When blood glucose is too high, insulin is released to lower it by storing it as glycogen

When blood glucose is too low, glucagon is released to increase it by releasing glucose from storage

Question 2

What is the relationship between calcitonin and PTH in homeostasis?

Accepted Answer

If blood calcium is too high, calcitonin is released by the thyroid to decrease calcium levels by turning calcium into bone and decreasing absorption by intestines + kidneys

If blood calcium is too low, PTH is released by the parathyroid to increase calcium levels by taking calcium from bones and increasing absorption by intestines + kidneys
