1

What is inflammation?

The reaction of the blood vessels, leading to the accumulation of fluid and leukocytes in the extravascular tissues

2

What is the function of inflammation?

A protective response
- eliminate microbes and toxins
- eliminate necrotic cells and tissues
- prepare for tissue repair

3

What do neutrophils do?

First responder (acute inflammation) bacterial or fungal infection

4

What forms pus?

Increased activity and death of neutrophils

5

What general percentage of WBC's do neutrophils make up?

60%

6

What do lymphocytes do?

Chronic inflammation
- T cell and B cell response/activation

7

What general percentage of WBC's do lymphocytes make up?

30%

8

What do monocytes do?

Long lived Phagocyte that present pathogen parts to T cells

9

What are monocytes when they are in tissue?

Macrophages

10

What general percentage of WBC's do monocytes make up?

5-6%

11

What do eosinophils do?

Parasite and Allergic response

12

What general percentage of WBC's do eosinophils make up?

2-3%

13

What do basophils do?

Allergic and antigen response and releasing the chemical histamine

14

What are basophils when they are in tissue?

Mast Cells

15

What general percentage of WBC's do basophils make up?

<1%

16

What is the order from largest to smallest of the WBC's?

Neutrophils
Lymphocytes
Monocytes
Eosinophils

19

Are thrombocytes WBCs?

No they are platelets

20

What is the function of thrombocytes?

To plug up holes

21

What is the life span of an RBC?

120 days

22

What is the life span of WBC?

days to years

23

What is the life span of a platelet?

8 days

24

What are the two types of inflammation?

Acute and Chronic

25

What is the duration and onset speed of acute inflammation?

Rapid onset and short duration (min/hours/days)

26

Is there edema with acute inflammation?

Yes

27

What type of leukocyte is predominantly present with acute inflammation?

Predominantly neutrophils, but also eosinophils and antibody mediated

28

What is the duration and onset speed of chronic inflammation?

Slower onset
Long duration (wks, months, years)

29

What are some characteristic appearances of chronic inflammation?

Presence of new blood vessels, fibrosis, and tissue necrosis

30

What type of leukocyte is predominantly present with chronic inflammation?

Predominantly macrophages and lymphocytes
