 Like all other body systems, the immune system helps the body maintain homeostasis.  Which statement best describes how the immune system does this?

• it breaks down food to provide cells with nutrients
• it gathers information through the senses and controls all other body systems
•  it transports oxygen and carbon dioxide

• natural passive
• natural active
• artificial passive
• artificial active

Production of IgE and degranulation of mast cells are involved in

• contact dermitis
• anaphylaxis
• Arthus reaction
• both a and b

How do T cells and B cells help build the body’s immunity to disease?

• T cells and B cells are skin cells that secrete oils which kill pathogens as they come in contact with the body’s surface.

• T cells and B cells attach themselves to antigens, gradually absorbing each antigen until it is no longer a threat to the body.

• When a body is exposed to a certain pathogen, T cells and B cells remember that pathogen and produce antibodies to fight that pathogen.

• Scientists extract T cells and B cells from a killed or weakened pathogen; when injected into a body, these cells trigger the body to make antigens for that pathogen.
