Quizplus · Accepted Answer

Vitamin D plays a crucial role in bone growth by assisting in the absorption of calcium and phosphorus from the intestinal tract, which are necessary for the formation and maintenance of bones. Synthesizing 7-dehydrocholesterol, mobilizing calcium from the bone, and secreting calcitonin are not the main functions of vitamin D in bone growth. Vitamin D assists in the absorption of calcium and phosphorus, which are necessary for bone growth and maintenance. Synthesis of 7-dehydrocholesterol occurs in the skin and is a precursor for vitamin D production when exposed to UV light. Mobilization of calcium from the bone is regulated by hormones such as parathyroid hormone, not vitamin D. Vitamin D also does not secrete calcitonin, which is produced by the thyroid gland.
