What Is Calcium?
Calcium is one of the essential minerals. The parathyroid gland controls the amount of calcium in the blood by measuring its levels and managing them through sending signals to the kidneys and bones. It instructs them to store or release calcium from bones, excrete it through urine, or absorb it via the kidneys. Additionally, Vitamin D facilitates the absorption of calcium from the digestive system.
The functions of calcium include:
Building bones.
Helping muscle movement and transmitting nerve messages from the brain to different body parts.
