0

Red blood cells

Transport oxygen and carbon dioxide

Erythrocytes

1

Platelets

Cells without nuclei

Initiate blood clot

2

White blood cells

Leukocytes
In blood and lymphatic system

3

Basophils

Release histamine; promote T cell development

4

Eosinophils

Kill large parasites by discharging destructive enzymes

5

Neutrophils

Engulf large invading pathogens (70% WBC)

6

Mast cells

Release histamine when damaged

7

Monocytes

Become macrophages

8

Macrophages

Engulf and digest microorganisms

9

Dendritic cells

Present antigen to T-cells

10

B cells

Differentiate to form plasma cells and memory cells (form in bone marrow)

11

Plasma cells

Secrete antibodies (weapons to destroy foreign invaders)

12

T cells

Kill virus infected cells (produced in the thymus)

13

Natural killer cells

Attack and lyse virus infected or cancerous cells

14

Complement proteins

Group of proteins help lyse invaders

15

Interferons

Release by virus-infected cells; ACTIVATE PHAGOCYTES; stimulate production of proteins in neighboring cells that'll inhibit viral replication

16

6.5 opsenization

Coating of pathogen with Ab's and triggering of phagocytic cells
