Skin Functions

Regulation of Body Temperature

*Constriction and Dilation* of blood vessels affect the amount of heat that escapes from the skin into the surrounding air. AND *Sweat Glands* are stimulated in response to heat and are inactive in cold temperatures.

Functions of the Skin

Regulation of Body Temperature, Adipose, Synthesis of vitamin D

Sensory Reception

The dermis contains numerous sensory receptors for heat, cold, pain, touch & pressure. It detects information about the environment & also serves as a means of communication between individuals.

Synthesis of Vitamin D

Precursors of vitamin D are found in the skin. When the skin is exposed to ultraviolet light, these precursors are converted into active vitamin D

Protection

The skins forms a protective covering over the entire body. It protects against water loss with keratin in the cells, invading organisms, ultraviolet lite with melanin, other injuries.

Adipose

is a subcutaneous tissue (fat) that helps insulate the body.
