Categories of White Blood Cells

Question 1

Types of Granulocytes

Answer 1

Neutrophils Eosinophils Basophils

Question 2

Types of Agranulocytes

Answer 2

Monocytes Lymphocytes

Question 3

Neutrophils (define)

Answer 3

Neutrophils consume bacteria by phagocytosis. They have a multi-lobed nucleus, clear-staining cytoplasm, and inconspicuous granules.

Question 4

Eosinophils (define)

Answer 4

Contribute to the destruction of parasites and to allergic reactions by releasing chemical mediators such as histamine.

Question 5

Answer 5

Basophils release histamine, which attracts WBC to the site of inflammation and widens blood vessels. They are large, purple-staining cytoplasmic granules; bilobed nucleus.

Question 6

Monocytes (define)

Answer 6

Monocytes give rise to macrophages, which consume bacteria, dead cells, and cell parts by phagocytosis. They are gray-blue cytoplasm with no granules; U-shaped nucleus.

Question 7

Lymphocytes (define)

Answer 7

Lymphocytes attach to damaged, diseased cells, or disease-causing organisms; produce antibodies. They are round nucleus that almost fills the cell.
