Leukocyte differential count.

Question 1

Name 5 kinds of leukocytes in blood and their categorization?

Answer 1

Polymorphonuclear granulocytes : neutrophils, eosinophils and basophils.
Mononuclear agranulocytes: Monocytes and lymphocytes.

Question 2

Answer 2

Produced at varying rates according to the changing needs of the body.

Question 3

What is WBC differential count?

Answer 4

Meander movement, count 100 leukocytes. Differentiate and sort into populations based on morphological appearance.

2. have a single large, non-segmented nucleus and few granules

Question 6

Answer 6

phagocytic specialist,first defenders during bacterial innflamm, important in innflammatory response.

hypersensitivity conditions, internal parasite infection

Question 8

Basophils are associated with?

Answer 8

allergic reactions and innflammations (tissue derivates = mast cells)

Question 9

Answer 9

Histamine and heparin.

Question 10

Categorize cells of lymphocytes?

Answer 10

B-cells hormonal defenders
T-cells cell-cell mediatet immune response
-T-helper, initiator
