Group 2: The swelling, redness and fever are all part of the infant’s [24.1] immune response which provides protection against a broad array of pathogens.  Immune cells in this response include phagocytic cells antigen presenting cells like [24.2] and [24.3].  These cells recognize a pathogen when [24.4] on the immune cell’s cytoplasmic membrane bind to [24.5] on the pathogen.  These cells can then engulf the pathogen into a [24.6] which fuses with a [24.7] to degrade the pathogen.  Then a(n) [24.8] from the pathogen is presented on the surface of the immune cell via the [24.9].  This can activate [24.10] cells that release [24.11].
