How does the skeletal system affect blood calcium levels?

The skeletal system acts as a storage site for calcium.


The body deposits calcium in the bones when blood levels get too high, and it releases calcium when blood levels drop too low.

Ca Homeostasis

When blood levels of calcium get too high, the thyroid gland releases calcitonin, which stimulates calcium uptake by the bones.

When blood levels of calcium get too low, the parathyroid glands release parathyroid hormone, PTH, which stimulates the release of calcium from the bones.
