Where is most calcium found in the body?

Muscles
Blood
Bones
Skin

The correct answer is: Bones

Most calcium in the body is stored in the bones. Approximately 99% of the body's total calcium content is found in bones and teeth, where it plays a crucial role in providing structural support and strength. The remaining 1% circulates in the blood and is essential for various physiological functions, including muscle contraction, blood clotting, and nerve transmission. While calcium can also be found in smaller amounts in muscles and skin, bones are the primary reservoir for this vital mineral, making them the predominant location of calcium in the body. This emphasizes the importance of adequate calcium intake for maintaining bone health and preventing conditions like osteoporosis.
