How does the parathyroid regulate calcium?

How do parathyroid and calcitonin regulate calcium levels?

Parathyroid hormone (PTH) and calcitonin are two hormones that help regulate calcium levels in the body. PTH increases calcium levels by promoting the release of calcium from the bones and increasing the absorption of calcium from the intestines. Calcitonin, on the other hand, decreases calcium levels by inhibiting the release of calcium from the bones and decreasing the absorption of calcium from the intestines. Together, these two hormones help to maintain calcium levels within the normal range.
