5

Question 4

difference between leukocytes and red blood cells (RBCs)

Answer 4

leukocytes have nuclei RBCs do not

Question 5

extensions called lobes

Question 6

what distinguishes different types of WBCs

shape of the nucleus number of lobes appearance and color of granules

Question 7

Cell organelles form

Answer 7

granules

Question 8

what is more easily seen in some types of leukocytes

Answer 8

granules

Question 9

criteria to distinguish and quantify WBCs in the lab

Answer 9

Wright Stain Leukocytes in blood Measurements of leukocytes

Question 10

Wright Stain

Answer 10

combined from Methylene Blue and Eosin used to treat prepared slides of blood some WBCs are named based on their affinity to its components

Question 11

Leukocytes are nearly colorless. True or False

Answer 11

colorless

Question 12

Methylene Blue, acid or base

Answer 12

alkaline (basic)

Question 13

Eosin, acid or base

Answer 13

acidic red

Question 14

What two groups are leukocytes are separated into?

Answer 14

Agranulocytes- generally hard to see granules

Granulocytes- easily seen granules

Question 15

Agranulocytes

Answer 15

typically hard to see granules

lymphocytes monocytes

Question 16

lymphocytes

Answer 16

smallest of WBCs can not see granules nuclei are spherical and fill them difficult to see a thin rim of cytoplasm

Question 17

what leukocyte are these

Answer 17

lymphocytes

Question 18

monocytes

Answer 18

largest leukocytes

can’t see granules

can see clear to light-blue cytoplasm surrounding the nucleus

nucleus is bi-lobed

transform into macrophages which enter other body tissues

Question 19

what leukocyte is this

Answer 19

monocytes

Question 20

granulocytes

Answer 20

can see granules

neutrophils

eosinophils

basophils

Question 21

neutrophils

Answer 21

have nuclei with several lobes, typically 3-6

equal attraction to components of wright stain

granules are pale lavender

Question 22

what leukocyte is this

Answer 22

neutrophils

Question 23

eosinophils

Answer 23

affinity for eosin in Wright Stain

granules are pink-red

Question 24

what leukocytes are these

Answer 24

eosinophils

Question 25

basophils

Answer 25

affinity for Methylene Blue (basic) in Wright Stain large, chunky, dark blue-purple granules so dark and large it can be hard to see the nucleus

Question 26

what leukocyte is this

Answer 26

basophil

Question 27

what is used to measure leukocytes

Answer 27

differential WBC count number of WBCs per unit volume of blood

Question 28

differential WBC count

Answer 28

compares percentages of each of the 5 leukocytes to what is expected in healthy blood

Question 29

percentage of neutrophils in healthy blood

Answer 29

normally 50-70%

Question 30

percentage of lymphocytes in healthy blood

Answer 30

25-35%

Question 31

percentage of monocytes in healthy blood

Answer 31

4-6%

Question 32

percentage of eosinophils in healthy blood

Answer 32

1-3%

Question 33

percentage of basophils in healthy blood

Answer 33

less than 1%

Question 34

what do differentiating percentages of leukocytes from healthy blood provide

Answer 34

diagnostic info based on different functions of WBCs

Question 35

what elevates neutrophils

Answer 35

bacterial infection

Question 36

lymphocyte rapid increase is associated with

Answer 36

antibody production

Question 37

elevated eosinophils can indicate

Answer 37

parasitic worm infection

Question 38

more numerous basophils are associated with

Answer 38

chronic inflammation

Question 39

what are the only leukocytes with more than 2 lobes on its nucleus

Answer 39

neutrophils

Question 40

what are the most common leukocytes (agranulocytes and granulocytes)

Answer 40

lymphocytes- agranulocytes neutrophils- granulocytes

Question 41

What leukocytes are agranulocytes

Answer 41

lymphocytes monocytes

Question 42

what leukocytes are granulocytes

Answer 42

neutrophils eosinophils basophils
