How does the skin aid in maintaining the calcium and phosphate levels of the body?
Correct answer
D
Rationale
The skin aids in maintaining calcium and phosphate levels in the body by producing Vitamin D when exposed to sunlight. Vitamin D is crucial for the absorption of calcium and phosphate from the diet, vital for bone health, and various physiological functions. When UV radiation penetrates the skin, it triggers the conversion of a compound into Vitamin D, which then facilitates the absorption of calcium and phosphate in the intestines.
