feedback4="'''Correct!''' Vitamin D3 is absorbed from the intestine or formed in the skin by the action of UV light on 7-dehydrocholesterol. It is then converted to 25-OH D3 in the liver by 25-hydroxylase. Next it is converted to its active form, calcitriol in the kidney. Calcitriol stimulates resorption of calcium and phosphate from bone and an increase in the amount of calcium and phosphate absorbed from the intestine.
