Immune System Test

A white blood cell that makes antibodies

• T cell
• bacteria
• B cell
• mast cell

These cells are responsible for identifying the "enemy" in an immune response.

• Killer-T Cells
• Antibodies
• Helper-T Cells
• B Cells

Example of 3rd line of defense.

• T cells and B cells reacting to pathogens
• Phagocytes engulfing pathogens
• Hydrochloric acid killing pathogens
• Mucus and cilia catching pathogens

These cells remain in the blood stream after an immune response.

• Memory B and T Cells
• Killer T Cells and B Cells
• Helper T  and B Cells
• Suppressor Cells and Macrophages

Proteins produced by B cells and designed to mark antigens to be destroyed, specific to the antigen.

• Antigens
