To geta better answer, Google American Heart Association articles from January 2008 and after, with Dr. Wang, Harvard researcher, who stated that smooth muscle contains Vitamin D receptors. Offhand, most likely because Vitamin D enables calcium uptake in the body and calcium is needed in proper amounts for muscle/nerve coordination (proper calcium/sodium/magnesium balance).
endocrine system
Ultraviolet A (long wavelength) initiates production of vitamin D and melanin (tanning). Ultraviolet B (short wavelength) damages the skin causing sunburns and in some cases cancers.
Vitamin D production is triggered by exposure to UVB rays, which are absorbed by the skin. In the integumentary system, the skin acts as a barrier between the external environment and the body, and it plays a crucial role in synthesizing vitamin D when exposed to sunlight. Vitamin D is essential for maintaining healthy skin, bones, and immune function.
True, provided you are exposed to the sun. Sunlight enables your body to make vitamin D. For this reason, vitamin D is sometimes called the sunshine vitamin.
The term "vitamin D" refers to several different forms of this vitamin. ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D2 synthesized by plants. Vitamin D3 is synthesized by humans in the skin. D is the fourth letter in the Latin alphabet and the vitamin D was the fourth vitamin discovered.
Vitamin D boosts your immune system, including lowering the risk of Influenza, it can prevent cancer and cardiovascular disease and can help with depression and generally reducing the risk of weakness. it supports the calcium.
No, it does not produce vitamin D.
endocrine system
Vitamin D is found in eggs, liver, milk, oily fish and margarine. It is very important. It is required for calcium absorbtion and storage. There are a number of deficiency diseases that can be gotten if vitamin D is not eaten. Some examples are rickets, weak bones which eventually become deformed and hearing problems.
Milk is a good source of vitamin D.
Vitamin D is necessary for strong and healthy bones and teeth. Vitamin D may also the help immune system and protect against some cancers. The childhood disease rickets, osteoporosis in older adults, and some onsets of Alzheimer's disease are thought to be associated with Vitamin D deficiency.
Vitamin D improves the absorption of zinc, magnesium, calcium and phosphate in the body. This vitamin prevents rickets and improves the health of bones.
Lack of vitamin D can cause Rickets in children. Rickets is the softening of bones. Vitamin D plays a part in bone health because it helps us absorb calcium Lack of vitamin D also puts you at risk of cardiovascular diseases. Lack of vitamin D has been linked to people with high blood pressure
The sun
The absorption of UV light into the skin converts a precursor molecule into vit. D
No, vitamin D is not from jade stone. Vitamin D is an animal product. Good food sources of vitamin D are milk, eggs, fish, beef, etc. We can also produce vitamin D in our skin when it is exposed to ultraviolet radiation (usually from the sun).
There is no known good natural source of vitamin D other than exposure to sunlight. If needed, there are always Vitamin D supplements, however these aren't as efficiently absorbed compared to the natural source.
