Proper blood calcium levels are required for muscle contraction, nerve function, and other critical activities in the body
How does the body maintain homeostasis in response to decreased blood calcium levels? Discuss the main gland, hormone, and target of the hormone.
What will be an ideal response
In response to decreased blood calcium levels, the parathyroid glands release parathyroid hormone (PTH) which stimulates osteoclasts to liberate calcium from bone and into blood. PTH also encourages the digestive system to absorb more calcium and the kidneys to retain more calcium in blood.
