Natural Killer Cell
Where are T Cells developed?
Thymus
What is the role of Helper T Cells in the immune response?
They activate immune response
Which type of white blood cell becomes plasma cells and produces antibodies?
B Cell
What is the role of the complement system in the immune response?
Destroying foreign invaders
What can activation of the complement system lead to?

Basophil cells
Which cells stick to the surface and go through blood vessels to eat up foreign invaders?
Macrophages
Which cells are activated when they bind to MHC II and release chemicals to activate other cells?
Helper T cells
Which cells look for infected cells and make copies of themselves for future defense?
Cytotoxic T cells
Which cells produce antibodies?
B cells
Which type of antibodies can cross the placenta and attack RH (+/-) antibodies?
IgG
Which type of antibodies are secreted in saliva, tears, and nasal fluids?
IgA
Which type of cells release histamine and are involved in allergic responses?

Antigens
What is the difference between passive and active immunity?
Active immunity is when the body learns about something and takes care of it, while passive immunity is when antibodies are given through treatments.
Test your knowledge of the different types of white blood cells and their functions in the immune response. Learn about T cells, B cells, natural killer cells, macrophages, and neutrophils, and understand how they contribute to both specific and non-specific immune defenses. Explore the roles of basophils and eosinophils, and discover the important functions of macrophages in the immune system. Challenge yourself to identify the major differences between these white blood cells and their unique contributions to immunity.
