21
Q

the largest organ of the body that forms a physical barrier between the external environment and internal environment that it serves to protect and maintain

A

the integuymantary sytem

22
Q

skin, hair, nails, glands

A

integumentary system

23
Q

physical barrier contains keratin, which toughens cells, fat cells to cushion blows; and both pressure and pain receptors, which alert the nervous system, to possible damage

A

mechanical damage (bump)

24
Q

has relatively impermeable keratinized cells; contains pain receptors, which alert the nervous system to possible damage

A

chemical damage (acids and bases)

25
Q

has unbroken surface and “acid mantle” (skin secretions are acidic and thus inhibit microbes, such as bacteria0macrophages phagocytize bacteria: plays important role in inflammation; holds and conveys tissue fluid phagocytes ingest foreign substances and pathogens, preventing them from penetrating into deeper body tissues

A

microbe damage

26
Q

melanin produced by melanocytes offers protection from uv damage

A

ultraviolet radiation (damaging effects of sunlight or tanning beds)_

27
Q

contains heat/pain receptors

A

thermal damage (heat/cold)

28
Q

contained perspiration produced by sweat glands

A

acids in excretion of urea and uric acid

28
Q

contains water- resistant glycolipid and keratin

A

desiccation (drying out)

29
Q

by activating sweat glands and by allowing blood to flush into skin capillary beds so that heat can radiate from skin surface

A

heat loss

30
Q

by not allowing blood to flush into skin capillary beds

A

heat retention

31
Q

modified cholesterol molecules in skin converted vitamin D in the presence of sunlight

A

synthesized vitamin D

32
Q

capable of being hard and tough due to keratin producing cells

A

epidermis

33
Q

tear resistant

A

dermis

34
Q

*anchors the skin to underlying organs
*not technically part of the integumentary system,
*composed of adipose tissue
*serves as a shock absorber and insulates deeper tissues

A

hypodermis

35
Q

occurs when sebaceous gland ducts are blocked by sebum

A

acne

36
Q

if the accumulated material oxidized and dries, it darkens, forming a

A

blackhead

37
Q

occur when there is prolonged pressure on specific areas of the body that are susceptible to friction and shear force injuries

A

decubitus ulcer

38
Q

restriction of the blood supply results in

A

cell death

39
Q

an itchy, red, peeling condition of the skin between the toes, resulting from an infection with the fungus TINEA PEDIS

A

athelete’s foot

40
Q

tissue damage and cell death caused by intense heat, electricity, UV radiation (sunburn) or certain chemicals (such as acids) which denature proteins and cause cell death in the affected

A

burns

41
Q

body fluids seep along with protein and electrolytes, causing dehydration and electrolyte imbalance that can lead to kidney shutdown and circulatory shock

A

burns

42
Q

healthy tissue

A

normal

43
Q

only the surface of the epidermis is affected

A

first degree burn

44
Q

deeper injury and causes blistering

A

second degree burn

45
Q

burns involve all the layers of the skin

A

third degree burn

46
Q

burns extended into the muscle and bone

A

fourth degree burn

47
Q

*least malignant
*cells of the stratum basale, altered so that they cannot form keratin, no longer honor the boundary between epidermis and dermis

A

basal cell carcinoma

48
Q

*arises from cells of stratum spinosum
*grows rapidly can metastasize to adjacent lymph nodes if not removed

A

squamous cell carcinoma

49
Q

*cancer of melanocytes
*some develop from pigmented moles and appears as a spreading dark patch
*often deadly with 50% chance of survival

A

melanoma

50
Q

what are the abcde’s mole or melanoma

A

asymmetry
border
color
diameter
evolving

51
Q

one half of mole does not match the other

A

asymmetry

52
Q

the edges are irregular, ragged, notched, or blurred, normal moles are round/oval

A

border

53
Q

the mole is not evenly colored. it may include shades of brown or black, or patches or pink, red, white or blue

A

color

54
Q

the spot is larger than 6 mm across

A

diameter

55
Q

the mole is changing in size, shape or color

A

evolving
