Identify functions of calcium within the body.

  • A. Clotting
  • B. Hardens bone
  • C. Nerve conduction and muscle contraction
  • D. All of the above.
Correct Answer: D

Rationale: The correct answer is D because calcium plays essential roles in clotting, bone health, nerve conduction, and muscle contraction. Calcium is crucial for the coagulation cascade in clotting, is a key component of bone mineralization, is required for neurotransmitter release in nerve conduction, and is involved in muscle contraction by regulating the interactions between actin and myosin. Choices A, B, and C are incorrect individually because they only represent some of the functions of calcium, whereas choice D encompasses all the vital functions of calcium in the body.
