What is one way that calcitonin and parathyroid hormone maintain homeostasis?
A. Calcitonin stimulates the bones to excrete calcium
calcium levels are too high, whille parathyroid hormone stimulates the bones
to absorb calcium when calcium levels are too low.
B. Calcitonin stimulates the kidneys to excrete calcium when calcium levels too high, while parathyroid hormone stimulates the
kidneys to absorb calcium when calcium levels are too low.
o C. Calcitonin stimulates the bones to absorb calcium
calcium levels
low, while parathyroid hormone stimulates the bones
to excrete calcium when calcium levels are too high.
• D. Calcitonin stimulates the kidneys to absorb calcium O when calcium levels are 100 low, while parathyroid hormone stimulates the
kidneys to excrete calcium when calcium levels are 100 high.
