Mineral homeostasis refers to the body's ability to maintain stable levels of essential minerals, such as calcium, potassium, and sodium. This balance is crucial for various physiological functions, including nerve transmission, muscle contraction, and bone health. The body regulates mineral levels through absorption, storage, and excretion processes, primarily involving the kidneys and gastrointestinal tract. Hormones play a significant role in mineral homeostasis. For instance, parathyroid hormone helps regulate calcium levels by promoting its release from bones and increasing absorption in the intestines. Similarly, aldosterone helps control sodium and potassium balance, ensuring that the body functions optimally and maintains overall health.
