Q

calcitonin

what do they do and where are they released from?

A

thyroid
targets bones and kidneys to lower blood calcium by inhibiting release of calcium fro bone and reabsorption of calcium by kidneys (high calcium can lead to kidney stones, among other things)

Q 
parathyroid hormone (PTH)
what do they do and where are they released from?
A

parathyroid
raises blood calcium levels by stimulating the bone cells to release calcium, the intestine to absorb calcium from food, and the kidneys to reabsorb calcium

progesterone

what do they do and where are they released from?

A

ovaries

promotes growth of the uterine lining and prevents uterine muscle contractions

21
