Question

The bones,kidneys,and intestine are target organs of this calcium-regulator hormone.
A) T3and T4
B) PTH
C) ACTH
D) Oxytocin

Accepted Answer

PTH, or parathyroid hormone, is the calcium-regulator hormone that primarily acts on bones, kidneys, and intestines. It works to increase calcium levels in the blood by stimulating bone resorption, decreasing calcium excretion by the kidneys, and increasing calcium absorption by the intestines. T₃ and T₄ are not known terms or hormones, and ACTH and oxytocin are not relevant to calcium regulation.
