Detailed explanation-1: -The epidermal layer of human skin synthesizes vitamin D when exposed to UV radiation. In the presence of sunlight, a form of vitamin D3 called cholecalciferol is synthesized from a derivative of the steroid cholesterol in the skin.
Detailed explanation-2: -The integumentary system is the largest of the body’s organ systems, made up of the skin and its associated appendages. The integumentary system distinguishes, separates, and protects the organism from its surroundings, but also plays a key metabolic function, as the major region for vitamin D production.
Detailed explanation-3: -The integumentary system synthesizes vitamin D by using sunlight to fuel the chemical reactions needed to transform provitamin D3 to previtamin D3. The previtamin D3 can be stored until the body needs to convert it to vitamin D through isomerization or converted to lymisterol and tachysterol.
