Immunity
Immune Responses and Lines of Defence
Immune Cells
100
A disease in which the immune system makes an inflammatory response to a harmless antigen
What are allergies?
100
Disease-causing agents such as bacteria and viruses.
What are pathogens?
100
An example of this occurs when a baby receives antibodies through the mother’s blood.
What is passive immunity?
100
Occurs when the immune system responds to a pathogen in the same manner, regardless of the type of pathogen.
What is a non-specific immune response?
100
General type of white blood cells that fight disease & infection.
What are leukocytes?
200
Any antigen that causes an immune response, can be inhaled, ingested, or come into contact with skin
What is an allergen?
200
An organism that passes a pathogen from host to host.
What is a vector?
200
This process produces memory cells - cells that can launch a rapid response to a pathogen.
What is active immunity?
200
The body’s response to tissue damage or infection that triggers the release of cytokines & histamines.
What is the Inflammatory Response?
200
White Blood Cells that recognize and destroy specific pathogens in body fluids and cells
What are lymphocytes
300
When the immune system fails to recognize the body’s own molecules as “self,” or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens.
What is an autoimmune disease?
300
Part of the pathogen that the body recognizes as foreign.
What are antigens?
300
Drugs used to help the immune system fight bacterial disease/infection by interfering with the cell wall.
What are antibiotics?
300

This process immediately prevents pathogens from entering the body 

What is The First Line of Defence?

300
A lymphocyte that matures in the bone marrow - recognizes & responds to antigens
What are B Cells?
400
Occurs when the immune system is not functioning at its highest level. The body is unable to fight off infections properly
What is immunodeficiency?
400
large, Y-shaped molecules that with only 1 specific type of antigen
What are antibodies?
400
Occurs when leukocytes engulf and destroy pathogens
What is phagocytosis?
400

Occurs through immediately activating non-specific, cellular responses like inflammation, phagocytes (white blood cells), and fever to destroy invaders (innate immunity). 

What is The Second Line of Defence?

400
An activated B cell that produces antibodies.
What is a plasma cell?
500
This is the type of medication/drug used to treat seasonal allergies.
What is an antihistamine?
500
2 types of chemicals released by damaged tissue that communicates with other cells to activate the inflammatory response
What are histamines and cytokines?
500
Inactive, live-attenuated, DNA, and subunit are types of these.
What are vaccines?
500
Occurs when the immune system responds to a pathogen in a specific manner based on the type of pathogen in the body.
What is the specific (adaptive) immune response?
500
This type of T Cell destroys cells infected by viruses.
What is a killer (cytotoxic) T cell?
