belongs to cavity

Answer 16

parietal

Question 17

belongs to organ

Answer 17

visceral

Answer 18

allow them to slip past each other

lines cavity of joints

Answer 21

synovial membrane

synovial fluid

Question 23

what are three ways in which tissues defend our body

Answer 23

mechanical barriers, cilia, and chemical barriers

Question 24

example of mechanical barriers

Answer 24

skin and mucosae

Question 25

how are cilia helpful?

Answer 25

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

Question 26

examples of chemical barriers helping us

Answer 26

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

regeneration

Question 28

tissue is replaced with connective tissue

Answer 28

fibrosis

Question 29

what 5 major things happen in inflammation

Answer 29

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

Question 30

what are the 4 signs of inflammation from

Answer 30

the capillaries becoming dilated

Question 31

plasma fluids have what

Answer 31

clotting proteins

Question 32

WBCs become.....

Answer 32

phagocytic

Question 33

what 5 major things happen during organization

Answer 33

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.

Question 34

factors that affect tissue repair

Answer 34
