← Human Body & HealthIf an elderly patient experiences diminished kidney function, what effect is most likely on bone mineral density due to disrupted mineral homeostasis?
A)Increased osteoblast activity dominates
B)Elevated phosphorus enhances bone density
C)Vitamin D synthesis increases sharply
D)Reduced calcium absorption lowers bone density✓
💡 Explanation
Reduced kidney function impairs vitamin D activation, which decreases calcium absorption in the intestines; because less calcium is absorbed, the body mobilizes calcium from the bones to maintain serum levels, therefore bone mineral density decreases rather than increases because of the altered mineral homeostasis.
