What is one way that calcitonin and parathyroid hormone maintain homeostasis? A. Calcitonin stimulates the bones to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the bones to absorb calcium when calcium levels are too low. B. Calcitonin stimulates the bones to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the bones to excrete calcium when calcium levels are too high.
C. Calcitonin stimulates the kidneys to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the kidneys to excrete calcium when calcium levels are too high. D. Calcitonin stimulates the kidneys to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the kidneys to absorb calcium when calcium levels are too low.

Answer:
Parathyroid hormone is hypercalcemic in nature,i.e, it increases the blood calcium levels by stimulating calcium reservoirs to release calcium in the blood. Calcitonin works just opposite to parathyroid hormone. It is hypocalcemic in nature.
