calcium homeostasis
Calcium homeostasis is the body's process of maintaining stable calcium levels in the blood and tissues, which is crucial for many functions, including muscle contractions, nerve signaling, and bone health. The body regulates calcium through hormones like parathyroid hormone (PTH), which increases calcium levels when they are low, and calcitonin, which lowers calcium levels when they are high. Vitamin D also plays a key role by helping the body absorb calcium from food. This balance ensures that our body functions properly and that bones remain strong and healthy.

Calcium homeostasis refers to the body's ability to maintain stable levels of calcium in the blood, which is crucial for various functions like muscle contraction, nerve signaling, and bone health. The body regulates calcium through hormones like parathyroid hormone (PTH) and calcitonin, as well as vitamin D. When calcium levels drop, PTH is released, increasing calcium by promoting its release from bones, absorption from food, and reduced loss in urine. Conversely, when levels are high, calcitonin helps lower them. This balance ensures that calcium levels remain within a healthy range, supporting vital bodily functions.

Calcium homeostasis is the body's process of maintaining stable calcium levels in the blood and tissues, essential for functions like muscle contraction, nerve transmission, and bone health. The body uses hormones, particularly parathyroid hormone (PTH) and calcitonin, to regulate calcium levels. When calcium is low, PTH increases blood calcium by releasing it from bones, absorbing it from food, and retaining it in kidneys. Conversely, calcitonin lowers calcium levels when they are high. This balance ensures that the body functions properly, as both low and high calcium levels can cause health issues.
