Questions: Select the minerals involved in maintaining the bony matrix Sodium Phosphorus Lead Potassium Calcium Iron

The minerals involved in maintaining the bony matrix are:

• Phosphorus
• Calcium

Explanation:

• Phosphorus: This mineral is a critical component of the bone matrix. It combines with calcium to form calcium phosphate, which gives bones their hardness and strength.
• Calcium: This is the most abundant mineral in the body and is essential for the development and maintenance of strong bones and teeth. It is a major component of the bone matrix.

The other minerals listed (Sodium, Lead, Potassium, Iron) do not play a primary role in maintaining the bony matrix:

• Sodium: Important for fluid balance and nerve function, but not directly involved in bone matrix maintenance.
• Lead: A toxic metal that can actually harm bone health.
• Potassium: Important for muscle function and fluid balance, but not directly involved in bone matrix maintenance.
• Iron: Essential for blood production and oxygen transport, but not directly involved in bone matrix maintenance.

In summary, the minerals involved in maintaining the bony matrix are Phosphorus and Calcium.
