Medical literature on calcium homeostasis

Calcium homeostasis is the body's way of maintaining stable calcium levels in the blood, which are essential for functions like bone strength, muscle contractions, and nerve signaling. The body regulates calcium through hormones such as parathyroid hormone (PTH), which increases blood calcium when needed, and calcitonin, which lowers it. Calcium is absorbed from food in the intestines, stored in bones, and excreted via kidneys. Proper balance depends on these processes working together to keep calcium levels within a narrow range, ensuring overall health and proper functioning of tissues and organs.
