A white blood cell that makes antibodies

• T cell
• bacteria
• B cell
• mast cell

  A substance or part of a substance (living or nonliving) that the immune system recognizes as foreign and activates the immune system and reacts with immune cells or their products, such as antibodies.

• pathogen 
• allergen 
• antigen 
• antibody

B Cells differentiate into memory cells and this cell that secretes antibodies?

• nerve cells

• helper cells

• plasma cells

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

• Antigens
• Active Immunity
• Antibodies
• Antibiotics

The skin, mucous membranes, natural secretions, and natural flora are all part of the

• First line of defense

• Second line of defense

• Third line of defense

What attacks microbes indiscriminately?

• The adaptive immune system

• The innate immune system

• The lymphatic system

• The nervous system

The body’s nonspecific defenses against invading pathogens include

• antibiotics.
• mucus, sweat and tears.
• antibodies.
• Killer T cells.

If our body encountered an antigen for the first time, what would occur?

• B cells would be unable to make antibodies until antigens are presented through macrophage MHCs

• Antibodies would not exist until dendritic cells brought pathogens to the lymph nodes

• Immunity would be at its highest because antibodies for this specific antigen have not yet been depleted

• In order to make up for the deficit in B cell antibody production, helper and cytotoxic T cell production would increase

Infected human cells present antigens or viral proteins on their cell surface through what?

• Major histocompatibility complexes

• antibodies

• T Cell receptors

• cytokines

A secondary immune response will be faster when...

• The individual has encountered the pathogen already

• The individual's macrophages are on high alert

• The individual has encountered the pathogen and has memory B cells circulating

• Antibodies are produced by T cells
