Immune System

3. First phase of phagocytosis that releases chemicals to create inflammation to attract neutrophils
6. Neutrophils, macrophages, and dendritic cells are part of this non-specific immunity
9. When oxygen consumption increases causing enzymes to form that catalyze the creation of hydrogen peroxide which is toxic to antigens
11. Stem cells base that neutrophils and macrophages come from
12. B cells and T cells are part of this memory building immunity
14. Secrete antibodies that bind specifically to an antigen
15. Second phase of phagocytosis
17. Fourth phase of phagocytosis
18. Chemicals that stimulate and attract other immune cells
19. Cells with a slower but long lived response that activates lymphocytes and trigger fever

1. Cells that secrete cytokines to help stimulate other immune cells
2. First line of defense that is rich in enzymes and has a low pH to degrade bacteria
4. First line of defense that sloughs old cells
5. Third phase of phagocytosis where antigen is engulfed
7. Stem cell base that B cells, T cells, and Natural Killer cells come from
8. Cells considered part of either innate or acquired immunity that target virus-infected or abnormal cells and inject them with proteins to destroy them
10. Cells that kill infected or abnormal cells with enzymes and toxins
13. Antigen presenting cells that initiate acquired immune response by attaching to an antigen and presenting it to T cells
16. First responders attracted by chemical signals that capture and destroy antigens
