Which tissue is important in vitamin D metabolism?

Explanation:
Vitamin D metabolism starts in the skin. Ultraviolet B light converts 7-dehydrocholesterol in the epidermis to previtamin D3, which then becomes vitamin D3. This skin-produced vitamin D3 is carried to the liver for 25-hydroxylation and then to the kidney for 1α-hydroxylation to form the active hormone. So, the skin is the tissue that initiates vitamin D metabolism. The other tissues listed do not initiate this process.
