Immune System

Any organism that causes disease like a virus or bacteria is called:

• Antibiotics

• Antibody

• Pathogen

• Phagocyte

Part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically at that pathogen is called:

• Protective Barrier

• Inflammatory Response

• Immune Response

• Stomach acid

A protein produced by B cells of the immune system that destroys pathogens is called:

• Antigens

• Antibodies

• T-cells

• Lymphocytes

What are the two parts of the immune system

• Innate and Adaptive

• Passive and Aggressive

• Innate and Non-Specific

• Adaptive and Acquired

What is the body's first line (non-specific) of defense against infection by foreign organisms?

• antibodies

• lymph nodes

• white blood cells

• the skin

What is the term for a strong response to a harmless antigen in the environment?

• An allergy

• Cell-mediated immunity

• An autoimmune disease

• Inflammatory response

White blood cells are an important part of the human immune response. Two types of white blood cells, neutrophils and macrophages, act as phagocytes. Phagocytes perform which of the following functions in the human body? 

• They produce antibodies.
• They bind to antigens and develop into plasma cells.
• They form a barrier against pathogens.
• They engulf and destroy bacteria.

What is the "big cell" that eats viruses and bacteria?

• Macrophage

• T Cells

• B cells

• Antibodies

The innate immune system is...

• Always working and doesn't require any special preparation

• Needs to be "primed" before it can work to its full effectiveness

• Very specific and only defends against a specific pathogen

• Not very effective at preventing intruders

What chemical is released by the immune system in response to an allergen?

• Dopamine
• Histamine
• Insulin
• No clue
