In brief: Regulates calcium.

They make parathyroid hormone (PTH), which regulates the body's calcium and phosphate levels.
These levels are important for normal nerve and muscle function. PTH tells bone to break down and release calcium into the blood. In the gut, it converts vitamin D to its active form which absorbs more calcium. It also tells kidneys to allow less calcium and phosphate to leave the body through urine.

In brief: Calcium regulation.

The parathyroid glands are continously checking the calcium level in the blood.
If the level drops too low, the gland produces more parathyroid hormone (pth), which has several actions to promote calcium coming into the blood. The gland also contains c cells, which make a separate hormone, calcitonin, which has some effects on bone metabolism.
