parathyroid
The skin produces vitamin D when exposed to sunlight. Vitamin D levels are monitored by the thyroid gland, which produces a hormone when levels are low, causing the skin to produce vit. D.
The parathyroid gland is responsible for increasing blood calcium levels by stimulating calcium re-absorption in the kidneys and activating vitamin D, which helps in calcium absorption in the intestines.
vitamin c
Parathyroid hormone (PTH) is the hormone that activates vitamin D in response to low blood calcium levels. This activation of vitamin D helps to increase calcium absorption in the intestines and maintain normal calcium levels in the blood.
No, the sebaceous gland produces sebum, or skin oil.
The only way to reduce vitamin D in the body is to stop intake of vitamin D.
Urinary system...this doesnt sound right to me..anyone got any imput? Personally, I believe it's the endocrine system because hormones often activate vitamin D. Also, the integumentary system helps with the absorption of vitamin D and activates it as well. Thanks for your timely reply. I am completing an A & P assignment which asks me to choose from a list of key answers. All the others have been used, and the two remaining answers are a choice of either the reproduction or urinary systems. My guess is that the answer is ... a repeat of an answer before.
No. It, in fact, is the opposite. Vitamin D is absorbed in the intestine, converted by UV radiation in the skin, and then helps absorb Calcium into the body. Vitamin D deficiency can be caused by a few things, a diet low in Vitamin D, low sun exposure, or it could be caused by a tumor in the parathyroid gland (but if you have low Calcium, that is not possible).
vitamin d
vitamin D
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
Vitamin D is a fat-soluble vitamin, meaning it is able to be dissolved in fat.
