1

Increase of wbcs count is called?

Leukocytosis

4

What is a white blood cell estimate?

40 power, count number of wbcs per field for ten fields, divide total from 10 fields by 10, multiply by 2000=== wbc/microliter (uL)

What happens in the neutrophil proliferating pool.

Cell division

13

What happens in the neutrophil maturation pool?

Maturing not dividing

14

Mature neutrophil

15

What is mnp?

Marginal neutrophil pool- stuck to walls, waiting to help

16

What is found in the circulating neutrophil pool?

On the look out for bad things

Segmented neutrophil (mature)

21

Life span of mature neutrophil.

7-14 hours

22

The most common Immature cell in dogs?

Band neutrophil

23

Left shift?

Greater than 5% band cells after your final count (lots of Immature cell)

24

Why do left shifts happen?

Increased need for neutrophils

25

More than five segments.

Hyper segmented (right shift)

26

Why do we see hypersegmentstion?

We left it in a coagulant for too long, b12 deficiency

27

Causes of neutrophilia?

Muscle activity, bacterial infections, leukemia types

28

Causes of neutropenia?

Viral infection, bacteria infections, nutritional deficiencies

29

Where are lymphocytes found.

In the pleuripotent cell

30

Second most common cell in circulating blood?

Lymphocytes

31

Two types of lymphocytes?

Small and medium/large

32

Round cell, smaller than neutrophils, round to oval nucleus.

Small lymphocytes

33

Bizarre shaped lymphocytes

Large/medium lymphocytes.

34

Small lymphocytes can we confused with....

Rbcs

35

Functions of lymphocytes?

T cells- memory cells, B cells- immune surveillance

36

Third or fourth most common cell in circulating blood?

Monocytes

37

Largest cell!

Monocytes

38

Functions of monocytes?

Provide immunity, "garbage eater"

39

Once a monocytes leaves the bloodstream what is it called?

Macrophage

40

What causes mono cytosis?

Inflammatory diseases, infections, fevers, obstructions,

41

Third or fourth most common cell in blood?

Eosinophils

42

Where are eosinophils found?

Intestinal lining, uterus, respiratory tract, skin

43

For each eo in the blood, how many are in the tissue?

Eosinophil function?

Engulf bacteria

45

What causes eosinophilia?

Paratism, allergies

46

Rare cell found in circulating blood?

Basophils

47

Basophils

48

Causes of basophilia?

Heartworm, allergies, cushings, leukemia

49

Difference between eosinophils and basophils?

Basophils are darker
