19
Q

lubricating fluid that is viscous and allows for sliding between adjacent tissue layers

A

Hyaluronic acid

20
Q

what membrane contains no epithelium

A

synovial membrane

21
Q

lines cavity of joints

A

synovial membrane

22
Q

what do synovial membranes secrete?

A

synovial fluid

23
Q

what are three ways in which tissues defend our body

A

mechanical barriers, cilia, and chemical barriers

24
Q

example of mechanical barriers

A

skin and mucosae

25
Q

how are cilia helpful?

A

they can trap things and move them so they can be expelled from the body

26
Q

examples of chemical barriers helping us

A

cutaneous membrane has acid that will kill whatever is there and the stomach has chemicals that will try to kill toxins

27
Q

tissue being replaced with same kind of tissue

A

regeneration

28
Q

tissue is replaced with connective tissue

A

fibrosis

29
Q

what 5 major things happen in inflammation

A
  1. ) chemicals released by mast cells and macrophages
  2. ) these chemicals cause the capillaries to dilate and become more permeable
  3. ) white blood cells and plasma fluids leak into injured area
  4. ) plasma fluids have clotting proteins which construct a clot
  5. ) scab forms
30
Q

what are the 4 signs of inflammation from

A

the capillaries becoming dilated

31
Q

plasma fluids have what

A

clotting proteins

32
Q

WBCs become…..

A

phagocytic

33
Q

what 5 major things happen during organization

A
  1. ) blood clot is replaced by granulation tissue
  2. ) new capillary bed is established
  3. ) fibroblasts close margin of the wound (by secreting growth factors and collagen fibers)
  4. ) macrophages digest blood clot
  5. ) collagen fibers deposited.
34
Q

factors that affect tissue repair

A

circulation, age, and nutrition (need protein to make collagen fibers and need vitamins)

35
Q

healing of epithelial tissue

A

vitamin a

36
Q

repair of heart or nervous tissue

A

vitamin b

37
Q

connective tissue/blood vessels

A

vitamin c

38
Q

bones

A

vit d

39
Q

prevents fibrosis (scarring)

A

vit e

40
Q

assists in blood clotting

A

vit k

41
Q

forms nervous tissue

A

ectoderm

42
Q

forms epidermis

A

ectoderm

43
Q

gives us connective tissue

A

mesoderm

44
Q

hollow ball of cells

A

blastula

45
Q

gives us mescle

A

mesoderm

46
Q

mucosae and serosae come from this layer

A

endoderm
