Answer 22

Chronic inflammation

Question 23

Why does chronic inflammation perpetuate

Answer 23

Stimulate proliferation of fibroblasts &
Constantly recruit new inflammatory cells

Question 24

Chronic inflammation may lead to

Answer 24

Loss of function

Question 25

Chronic inflammation type not preceded by acute

Answer 25

Granulomatous Inflammation

Question 26

What accumulates at site of injury during Granulomatous inflammation

Answer 26

T-lymphocytes and macrophages

Question 27

t-lymphocyte and macrophage function in Granulomatous inflammation

Answer 27

Lymphocytes release cytokines Cytokines turn macrophage into epithelioid cells

Question 28

Epithelioid functions during Granulomatous inflammation

Answer 28

Cells fuse together forming multinucleated giant cells

Question 29

Granulomas consist of

Answer 29

Lymphocytes, macrophages, multinucleated giant cells

Question 30

Leukocytosis

Answer 30

increase circulating WBC's

Question 31

Continually dividing or mitotic cells (Tissue healing)

Answer 31

Stem cells divide and differentiate, replace lost cells

Question 32

Result of continually dividing cells (tissue healing)

Answer 32

Minimal tissue damage

Question 33

Quiescent Cells (tissue healing)

Answer 33

Don't divide regularly, divide if necessary

Question 34

Outcome of quiescent cells (tissue healing)

Answer 34

Regeneration - replace w identical tissue

Question 35

Non-dividing cells (tissue healing)

Answer 35

Not able to divide and regenerate Eg. neuron

Question 36

Outcome of non-dividing cells? (tissue healing)

Answer 36

Loss of functional capacity

Question 37

by first intention healing

Answer 37

would clean, necrotic tissue/edges close together

Question 38

by second intention healing

Answer 38

Large break, more inflammation, longer healing

Question 39

Leukocytes (WBC's) **PMNS**

Answer 39

Scavenge initial injury site

Question 40

Connective tissue cells

Answer 40

Prod. scar tissue

Question 41

Epithelial cells

Answer 41

Divide and extend across wound
