Electrolyte regulation refers to the body's ability to maintain the proper balance of electrolytes, which are minerals like sodium, potassium, and calcium that carry an electric charge. These electrolytes are essential for various bodily functions, including nerve signaling, muscle contraction, and hydration. The body regulates these levels through mechanisms such as hormone release and kidney function. The kidneys play a crucial role in electrolyte regulation by filtering blood and excreting excess electrolytes in urine. Hormones like aldosterone and antidiuretic hormone (ADH) help control the reabsorption of electrolytes and water, ensuring that the body maintains homeostasis. Proper electrolyte balance is vital for overall health and well-being.
