keeps water and other precious molecules in the body

prevents water loss from the bodies surface

made up of stratified squamous epithelium that is capable of keratinizing, or becoming hard and tough

made mostly of dense connective tissue

adipose tissue which serves as a shock absorber and insulates the deeper thissues from extreme temperature changes occuring outside the body. also makes up the curbes of woman :D

five layers of the epidermis

stratum basale, sponosum, granulosum, lucidum, and corneum

the fibrous protein that makes the epidermis a tough, protective outer layer

lies closest to the dermus and contains epidermal cells that receive the most adequate nourishment via diffusion of nutrients from the dermis

full of keratin.. die and form clear stratum lucidum

20-30 layers thick. accounts for about three-quarters of the epidermal thickness keeps deeper cells safe from hostile external environment(air) and from water loss. and helps body resist biological,chemical, and physical assults."beauty is only skin deep"

pigment that ranges in color from yellow to brown to black. Is produced by special cells called melanocytes(found in stratum basale).

when skin is exposed to sunlight, melanocytes produce more melanin which causes tanning

strong, stretchy envelope that helps hold the body together. inner layer of skin

two primary layers of dermis

pappilary layer and dermal papillae

cutaneous glands=(hair and hair follicles)

are founds all over skin except on the palms of hands and soles of feet, (main cause of acne)

product of sebaceous gland which is a mixture of oily substances and fragmented cells.(contains that kills bacteria)

produces sweat and some sodium chloride

causes muscles to contract when cold,(also causes goose bumps)

scalelike modification of the epidermis that corresponds to the hoof or claw of other animals.

is tissue damage and cell death caused by intense heat, electricity, uv radiation (sunburn), or certain chemicals (acids)

volume of fluid lost after body is burned.( seperates body into 11 different areas each accounting for 9% of the total body surface area.)

Question	Answer
integument	keeps water and other precious molecules in the body
keratin	prevents water loss from the bodies surface
epidermis	made up of stratified squamous epithelium that is capable of keratinizing, or becoming hard and tough
dermis	made mostly of dense connective tissue
hypodermis	adipose tissue which serves as a shock absorber and insulates the deeper thissues from extreme temperature changes occuring outside the body. also makes up the curbes of woman :D
five layers of the epidermis	stratum basale, sponosum, granulosum, lucidum, and corneum
keratinocytes	produce keratin
keratin	the fibrous protein that makes the epidermis a tough, protective outer layer
stratum basale	lies closest to the dermus and contains epidermal cells that receive the most adequate nourishment via diffusion of nutrients from the dermis
stratum spinosum	full of keratin.. die and form clear stratum lucidum
stratum corneum	20-30 layers thick. accounts for about three-quarters of the epidermal thickness keeps deeper cells safe from hostile external environment(air) and from water loss. and helps body resist biological,chemical, and physical assults."beauty is only skin deep"
melanin	pigment that ranges in color from yellow to brown to black. Is produced by special cells called melanocytes(found in stratum basale).
melanocytes	when skin is exposed to sunlight, melanocytes produce more melanin which causes tanning
dermis	strong, stretchy envelope that helps hold the body together. inner layer of skin
two primary layers of dermis	pappilary layer and dermal papillae
skin appendages	cutaneous glands=(hair and hair follicles)
sebaceous glands	are founds all over skin except on the palms of hands and soles of feet, (main cause of acne)
sebum	product of sebaceous gland which is a mixture of oily substances and fragmented cells.(contains that kills bacteria)
2 main sweat glands	eccrine and apocrine
eccrine	produces sweat and some sodium chloride
apocrine glands	make you smell musky
arrector pili	causes muscles to contract when cold,(also causes goose bumps)
nail	scalelike modification of the epidermis that corresponds to the hoof or claw of other animals.
burn	is tissue damage and cell death caused by intense heat, electricity, uv radiation (sunburn), or certain chemicals (acids)
