🧠 Explanation:

Calcium is the most abundant mineral in the human body, making up about 1.5–2% of body weight. It is essential for strong bones and teeth, as about 99% of calcium is stored in the skeletal system. Calcium also plays a vital role in muscle contraction, nerve transmission, blood clotting, and enzyme function. A proper calcium intake is necessary to prevent conditions like osteoporosis and maintain overall health. Dairy products, leafy vegetables, and fortified foods are primary dietary sources. Understanding calcium’s functions is important for biology, health studies, and general knowledge exams like PPSC.
