Concepts

  1. Natural Barriers

    "The physical and chemical barriers that prevent pathogens from getting into our body tissues in the first place are often overlooked. The most comprehensive barrier is the waterproof layer of skin th

  2. Inflammation Leukocytes

    "The human immune system is an extremely complex network of interacting cells and biological molecules. An immune response to infection develops in three overlapping stages, the first of which is trig

  3. Innate Immunity

    "All animals, even those with much simpler bodies than our own, respond to tissue damage in ways that resemble inflammation in humans. They have cells similar to leukocytes and defensive proteins that

  4. Adaptive Immunity

    "Humans and other warm-blooded animals have an additional defensive capability called adaptive immunity, which differentiates specifically between pathogens. Adaptive immunity is due to the actions of
