The Immune System

What is the main purpose of the immune system?

• support the body through bones and muscles
• get rid of waste from the body
• protect the body from pathogens
• move blood through the body

Cells that ingest pathogens are

• plasma cells
• phagocytic cells
• helper T cells
• antibodies

What do B cells produce?

• antigens
• macrophages
• T cells
• antibodies

Where do T cells mature?

• lymph node
• bone marrow
• thymus
• liver

What do antibodies attach to on the pathogen?

• Anti inflammatory
• Antigens
• Antiseptic
• Antibodies

Pathogens are recognized by their...

• antigens
• antibodies
• killer t-cells
• B-cells

Anything that triggers an immune response is a/n

• lymph cell
• antigen
• antibody
• neutrop

What is the function of antibodies within the immune system?

• Antibodies kill off any antigen that enters the body.

• Antibodies are only made when you are given a vaccination for specific antigens.

• Antibodies bind to specific antigens to flag for destruction.

• Antibodies are part of an external defense mechanism.

What happens after the second time you are exposed to a pathogen?

• The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier.

• The body's immune system will react the same was as it did during the first exposure.

• The body can only be exposed to a pathogen a second time if you do not have a vaccine.

• The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.

How do T cells differ from B cells?

• T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.

• T cells only make memory cells, and B cells only make antigens

• T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.

• T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
