Question

Quizplus · Accepted Answer

The skeletal system plays a major role in maintaining the normal concentrations of calcium and phosphate ions in body fluids. Calcium and phosphate are essential for a number of physiological processes, including bone growth and repair, nerve conduction, muscle contraction, and blood clotting. The bones store these minerals and release them into the bloodstream as needed to maintain proper levels.
