When skin gets warm, arriving oxygenated blood is diverted to the superficial dermis for the pur- pose of?
8. When skin gets warm, arriving oxygenated blood is diverted to the superficial dermis for the pur- pose of eliminating heat. The oxygenated blood gives a reddish col- oration to the skin.
Why do I get a tan?
22. A tan develops when the skin is exposed to the sun. The tan is a result of the synthesis of melanin in the skin. Melanin, in turn, helps prevent excessive skin damage by absorbing UV radiation before it reaches the deep layers of the epi- dermis and dermis. Within the epidermal cells, melanin concentrates around the nucleus, so it absorbs the UV light before it can damage nuclear DNA. A benefit of minimal sun exposure is that sunlight causes epidermal cells to convert a cholesterol-related steroid into cholecalciferol (Vitamin D3), which is important to bone mainte- nance and growth.
What is the effect of sunlight on the body?
29. (a) Ultraviolet radiation in sunlight converts a cholesterol-related steroid into vitamin D3, or cholecalciferol. This compound is then converted to the hormone calcitriol, which is essential for absorbing the calcium and phosphorus by the small intestine that is necessary for normal bone maintenance and growth. (b) The child can drink more milk. Milk is routinely fortified with cholecalciferol, normally identified as "vitamin D," which is easily absorbed by the intestines.
What happens to the dermis when the skin gets warm?
When skin gets warm, arriving oxgenated blood is diverted to the superficial dermis for the purpose of eliminating heat. The oxygenated blood imparts a reddish coloration to the skin. Describe the location of the dermis. The dermis ( a connective tissue layer) lies between the epidermis and the hypodermis.
Why does sunlight darken skin?
Exposure to sunlight or sunlamps darkens skin becausethe ultraviolet radiation they emit stimulates melanocytes in the epidermis and dermis to synthesize the pigment melanin.
How does aging affect skin?
Common effects of the aging process on the skin include epidermal thinning due to a decline in germinative cell activity; a decrease in melanocyte abundance; a reduction in sebaceous gland secretion; a decline in dendritic cell numbers; a reduction in vitamin D3 production; a decline in glandular activity; the stoppage of hair follicle functioning; and a slowing of the pace of the skin repair.
Why does sweat glands become less active?
As a person ages, the blood supply to the dermis decreases , and merocrine sweat glands become less active. Both changes make it more difficult for the elderly to coll themselves in hot weather.
Why does skin regenerate?
Skin can regenerate effectively even after undergoing considerable damage because stem cells persist in both the epithelial and connective tissue components of skin. In response to injury, cells of the stratum basale (germinativum) replace epithelial cells while mesenchymal cells replace lost dermal cells.
