calcium homeostasis

Calcium homeostasis refers to the regulation of calcium levels in the body to maintain stable and optimal concentrations in the blood and tissues. This process is vital for numerous physiological functions, including muscle contraction, nerve transmission, blood clotting, and bone health. Key organs involved in calcium homeostasis include the bones, kidneys, and intestines, with hormones such as parathyroid hormone (PTH), calcitonin, and vitamin D playing crucial roles. Understanding calcium homeostasis is essential for studying metabolic disorders, bone diseases like osteoporosis, and overall cellular function.
