Any substance that the white blood cells recognize as foreign is known as an?
Pathogen.Pathogens can be things like viruses or bacteria which have things called antigens on them. These antigens are proteins on the pathogen that let the body know that the pathogen is potentially dangerous. This induces the immune response.Hope this helps!

Antigen
Once the body encounters a pathogen and destroys it what is created?
Once the body activated, killer T cells it recognize pathogen and destroy them. In response that will create memory B cells and T cells specific to a certain pathogen, so if it ever came back it will be killed immediately.
Substances that the body recognizes as foreign are called?
Antigens Antibodies neutralize these molecules.
If the same pathogen invades the body twice it will be recognized and destroyed more quickly the second time because of what?
Memory B cells act like an internal vaccine because once it fights the pathogen off it will recognize it. This is how they make vaccines because they inject you with a small amount of the pathogen not enough to harm you so your memory B cells recognize it.
Does the first exposure to a pathogen result in a much faster immune response than the second exposure to the same pathogen?
After your first exposure to a pathogen, you have memory T-cells that will remember the antigen of the pathogen so in the future if you would come in contact with the same pathogen your body would recognize it right away and be able to kill it much faster.
