1

What are the 4 phases of injury and repair

1. Hemostasis
2. Inflammatory phase
3. Proliferation phase
4. Maturation phase

2

When does hemostasis occur

Immediately after injury

3

How long does the inflammatory phase last

1-6 days

4

How long does the proliferation phase last

3-20 days

5

How long does the maturation phase last

Day 9 and on

6

What is diapedesis

Squeezing through vessel walls

7

What is blood accumulated in tissue

Hematoma

8

What is blood accumulated in a joint

Hemarthrosis

9

What is the equation for capillary filtration pressure (CFP)

CFP=(CHP+TOP)-(THP+COP)

10

What is CHP

Capillary hydrostatic pressure

11

What is COP

Capillary osmotic pressure

12

What is hydrostatic pressure

Pressure exerted by a column of water

13

What is osmotic pressure

Pressure resulting from attraction f fluid by free proteins

14

Does hydrostatic pressure pull or push water

Pushes water

15

Does osmotic pressure pull or push water

Pulls water

16

What are the 3 polymorphonuclear leukocytes

1. Neutrophils
2. Basophils
3. Eosinophils

17

When are polymorphonuclear leukocytes released

The first 24 hours

18

What do neutrophils do

Phagocytosis and release protease and collagenase

19

What do basophils do

Release histamine and increase vascular permeability

20

What do eosinophils do

Phagocytosis

21

What are the 2 mononuclear leukocytes

1. Monocytes
2. Lymphocytes

22

When are the mononuclear leukocytes released

Hours 24-48

23

What are monocytes converted to

Converted to macrophages, collagenase, fribronectin, hydrogenperoxide, ascorbic acid, and lactic acid

24

When are monocytes most effective

In O2 rich environment

25

What do lymphocytes do

Supply antibodies

26

What do B lymphocytes do

Release antibodies into the bloodstream

27

What do T lymphocytes do

Assist B cells in regulation of cloning

28

What does hypoxia do (4)

1. Switch from aerobic to anaerobic metabolism
2. Decreases ATP production
3. Decreases cell membrane function
4. Increase cellular acidosis

29

How does hypoxia affect cell membrane function (3)

1. Na pump slows or stops
2. [Na] in cell increases
3. [H2O] increases, cell swells, bursts

30

What is the process of making collagen from fibroblasts (6)

1. Fibroblasts
2. Procollagen
3. Tropocollagen
4. Collagen fibrils
5. Collagen filaments
6. Collagen fibers
