Bones store most of the calcium supply of the body

Ture.

Bones serve as the body's primary storage site for calcium, holding about 99% of the body's total calcium supply.

This calcium is essential for maintaining the structural integrity of the skeleton, but it's also crucial for many other bodily functions:

• Nerve Impulses: Calcium is required for the transmission of nerve signals.

• Muscle Contraction: It plays a vital role in muscle function, including the beating of the heart.

• Blood Clotting: Calcium is a necessary factor in the blood coagulation process.

The body constantly regulates blood calcium levels by withdrawing calcium from or depositing it into the bones, a process managed by hormones like parathyroid hormone (PTH) and calcitonin.
