General
Human Immunology: The Body's Defense System
The human body has many tactics that is employs; continuously working to eliminate potential pathogens from its territory. This link takes you to a page with general information on the three lines of immune system defense.
Nonspecific Immunity
Our body’s first line of defense includes structures, and chemicals, processes that work to prevent pathogens entering the body. Read more about how the skin and mucous membrane help defend your body from invaders.
2. Leukocytes:
Leukocytes are white blood cells that can be categorized into one of two groups based on the presence or absence of small granules of material within. Each of the two following links will lead you to more detailed information.
There are two cell types that do their killing extracellularly (outside the cell). These include Natural Killer Lymphocytes(NK cells) and Eosinophils.
The complement system consists of specific proteins circulating in blood plasma. Most are inactive until they are cut by an enzyme and activated. The pattern of sequential activation of complements results in a cascade of events that ultimately protect the body.
