Answer 1

parathyroid glands

Step-by-step explanation:

If the serum calcium level falls, the parathyroid glands release PTH into the blood and this signals cells in bone (osteoclasts) to release calcium from the bone surfaces. PTH also signals the kidney to reclaim more calcium before it is excreted in the urine and also stimulates synthesis of the active form of vitamin D.

Answer 2

Answer: Option A) Parathyroid glands

Step-by-step explanation:

The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.

This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.
