Which of the following is a function of the musculoskeletal system?
- A. Stores vitamin D
- B. Supplies oxygen to cells
- C. Stores calcium and phosphorous
- D. Transports antibodies to cells
Correct Answer: C
Rationale: The correct answer is C because the musculoskeletal system stores calcium and phosphorous, which are essential minerals for bone health and muscle function. Calcium is stored in bones and released when needed for muscle contraction and other bodily functions. Phosphorous is also stored in bones and plays a crucial role in energy production and maintaining cell structure. The other choices are incorrect because storing vitamin D (A) is primarily done by the skin and liver, supplying oxygen to cells (B) is the function of the respiratory and circulatory systems, and transporting antibodies to cells (D) is the function of the immune system.
