The integumentary system acts as a barrier against pathogens, UV radiation, and dehydration, helping to protect the body from harmful external factors. It also plays a role in regulating body temperature and provides sensory information about the external environment through nerve receptors in the skin. Additionally, the integumentary system synthesizes vitamin D, which is important for multiple body functions.
You do not use it consciously, but your body uses it (from sunlight) to generate vitamin D.
The amount of vitamin D that can be made by the body is limited by factors such as sun exposure, skin pigmentation, age, geographic location, clothing coverage, and the use of sunscreen. Additionally, certain medical conditions or medications can affect the body's ability to produce vitamin D.
without vitamin D, your body can not create calcium for your bones. in the winter you must have at least 10 min. of sun light so your body can make the required calcium. vit. D can also be stored for later use.
Vitamin D is the vitamin that your body can store because it can be synthesized and stored in fat cells for later use. Vitamin C, on the other hand, is not stored in the body and any excess is excreted through urine.
