skin
```
in an average adult, it covers more than 3,000sqin of surface area , weighs more than 6lbs and is largest orang of the body
4 main functions:
-protection
-regulation
-sensation
-secretion
```
35
protection
one of the functions of skin; responsible for keeping bacteria and other harmful agents from penetrating deeper tissues; skin's protection also inhibits excessive loss of water and guards the body against excessive exposure to the sun's ultraviolet rays
36
regulation
under this function, skin serves to raise or lower body temperature as necessary
37
radiation
a regulatory process used when the body needs to lose heat, the blood vessels in the skin dilate bringing more blood to the surface for cooling
38
evaporation
a regulatory process that occurs when the sweat glands secrete more sweat for cooling
39
sensation
one of the functions of the skin, it describes how the skins microscopic nerve endings act as sensory receptors for pain, touch, heat, cold, and pressure
40
sensory receptors
specialized nerve cells that relay impulses from stimuli to the nervous system for response
41
perspiration
sweat secreted from the skin's millions of sweat glands
42
sebaceous glands
the oil-secreting glands of the skin
43
sudoriferous glands
refers to the two kinds of sweat glands:
- apocrine sweat glands
- merocrine sweat glands
45

an oily secretion that acts to protect the body from dehydration and possible absorption of harmful substances
46
epidermis
one of the two layers of skin; it's the outer layer of skin that varies in thickness; it can be divided into five strata:
- stratum germinativum
- stratum spinosum
- stratum granulosum
- stratum lucidum
- stratum corneum
47
dermis
one of the two layers of skin, it's sometimes called the corium or true skin; it is composed of connective tissue containing lymphatics, nerves and nerve endings, blood vessels, sebaceous and sweat glands, elastic fibers, and hair follicles;
has two subdivided layers:
-papillary layer (the upper layer)
-reticular layer (the lower layer)
48

it produces the ridges of the skin seen from fingerprints or footprints
49
reticular layer
| lower layer
