special white blood cells inside the lymph nodes
cells that are sent to the thymus for special training in spotting and attacking foreign cells. They are also called T cells
defenses that are in your body all the time and respond to every threat in the same manner. Examples of this are your skin, sebum, and tears.
What we call the wide range of defenses, such as the skin barrier and inflammation, that act in the same way, no matter what the attack. These are defenses you are born with, not defenses that result from a vaccination or the flu you may have had last year.
another part of your immune system which is composed of proteins manufactured by your liver and which destroy foreign bacteria. The proteins also cause body tissue to swell when needed. This would be like when your finger swells when you have a splinter in it
The swelling of tissue. It is an important part of your body's immune response
special kinds of chemicals that are released and sent to injured tissue which helps with increased blood flow to the hurt area and tissue swelling.
what we call the substance that is produced when bacteria is trapped and killed. It's made up of damaged tissue, living and dead bacteria and dead white blood cells
Cells that are developed in the bone marrow and are trained to spot and attack foreign cells. They are also called B cells.
A sophisticated system of defense that ensures your body doesn't get certain diseases more than once
Special proteins made by B cells that lock onto foreign antigens, flagging them for destruction
Killer T cells
Special T cells that attack and destroy cells that have been flagged for destruction by antibodies.
These occur when your immune system overreacts to non-harmful substances that get inside your body
Diseases in which the body forms antibodies against its own tissue
Immunity that is acquired without any action on the part of the body's immune system. An example of this is the immune protection a baby receives from the mother's milk.
Immunity that occurs when your immune system is exposed to and responds to, a specific threat
Active artificial immunity
Immunity from vaccinations
The first antibiotic to be widely used. It comes from a mold
Medicines made from chemicals which kill living organisms that invade our bodies.
