The body's calcium level is regulated by a gland in the endocrine system, it is called the Parathyroid Gland.
The parathyroid hormone
The thyroid gland produces calcitonin. The parathyroid gland produces PTH. Both hormones work together to regulate the amount of clcium in the blood and tissues.
Blood
The thyroid gland produces calcitonin which lowers blood calcium levels and the parathyroids produce parathyroid hormone which increases blood calcium levels.
The parathyroid glands produce and secrete parathyroid hormone which regulates calcium levels in the blood. Since it increases blood calcium levels, it promotes the function of osteoclasts, which reduce the calcium in bones and promote its increase in the blood stream.
explain how calcium is regulated by the endocrine system
Ionic calcium: Calcium absorption is closely related to blood levels of ionic calcium. It is locally regulated by the active form of Vitamn D, which promotes active calcium absorption. pg 900 Anatomy Book

The parathyroid hormone
"The amount of calcium in the blood is regulated by two organs: thyroid and parathyroid glands. Each gland produces hormones by sensing the amount of calcium in the blood. When calcium is high in the blood, the thyroid gland produces calcitonin, which results in the removal of excess calcium from the blood. When calcium is low in the blood, the parathyroid gland produces parathyroid hormone, which causes the release of calcium from bone into the blood."
True, blood calcium is very tightly regulated there are two types of bone cells that will either take up excess calcium if blood levels get too high or break down bone to release calcium if blood levels get to low. Both of these bone cells are controlled by the endocrine system in the body.
