6143398304	Mechanical trauma	Function 1 of skin, stratified squamous, keratinized epithelium provides a durable, but flexible surface	3
6143404598	Pathogens	Function 2 of skin, continuous barrier to invasion by microorganisms or pathogens that can cause disease contains cells of immune systems that destroy pathogens before they invade deeper tissues	4
6143413000	Environment	Function 3 of skin, Provides protection from ultraviolet light before it damages other tissues	5
6143422755	Sensation	Numerous sensory receptors that detect changes in internal and or external environment	6
6143426821	Thermoregulation	Process that relies on negative feedback loops for maintenance of a stable internal temperature	7
6143430788	Excretion	Waste products and toxins are eliminated from the body	8
6143433657	Keratin	In epidermis, resistant to mechanical trauma	9
6143436818	Stratum Basale	single layer of stem cells that rest on the basement membrane and appear slightly cuboidal or columnar rather than squamous	10
6148115303	Scarring, unable to regulate body temp, nerve damage, suppressed immune system, fluid homeostasis is affected	Complications of the integument(outer, protective layer) of burn victims	11
6148122370	UVB	UV radiation with shorter wavelength	12
6148125032	Shorter	Which has a higher energy associated with it, longer or shorter wavelengths	13
6148133566	premature skin aging, eye damage, skin cancers, suppress immune system	UVA and UVB rays play roles in:	14
6148142863	Damages the skin's cellular DNA in the nucleus, and produces genetic mutations that may lead to skin cancer	How does the UV radiation cause skin cancer	15
6148147949	Basal and squamous cell carcinoma	Nonmelanoma skin cancers	16
6148150422	UVA	UV radiation that penetrates to the dermis of the skin	17
6148154277	UVA UVB	UV radiation that promotes photoaging and wrinkles	18
6148163865	Dermis has collagen that is breaking down Epidermis has keratin that is breaking down	What is damaged causing the appearance of wrinkles in photoaging	19
6148170286	UVA	Tanning booths use this kind of radiation	20
6148173429	75	Tanning booths increase chance of developing carcinoma by this much percent	21
6148179398	UVB	Does not penetrate glass	22
6148185960	UVB	Contributes most to sunburn	23
6148187487	Sun Protection factor	How long it will take for UVB rays to redden skin. SPF 15 will take 15x longer for skin to redden than if you did not have it on	24
6148197234	15	Lowest SPF adequate	25
6148204575	Absorb the UV radiation before it penetrates the skin because of the thin, protective film on the surface of the skin	Chemical filters in sunscreen	26
6148209788	Reflect UV away from the skin because of the insoluble particles in sunscreen	Physical barriers in sunscreen	27
6148226427	Function of dermis	Provides blood supply for epidermis	28
6148228291	Function of dermis	Contains sensory receptors	29
6148231509	Function of dermis	Anchors epidermis in place	30
6148239077	Melanin is produced	Why do we tan	31
6148244089	Skin pigments	Determined by various amounts of orange-red-black protein pigment melanin	32
6148251769	Melanocytes in stratum basale of epidermis	What is melanin produced by	33
6148255214	Chemical reaction of melanin	2 molecules of amino acid tyrosine; chemically bonded by a series of reactions catalyzed by enzyme tyrosinase	34
6148264943	Oxidation of melanin	What makes the tan go away	35
6148270116	Function of melanin	Protect keritoncytes from UV damage	36
6148272655	Function of melanin	Reduces synthesis of Vitamin D production, prevents overproduction	37
6148283302	Cells are dead, therefore cant divide	Why is there only cancers in basal and squamous? Why not other layers	38
