Chain A   (DEFI_ANOGA | Q17027)
biological process
    GO:0006952    defense response    Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0006959    humoral immune response    An immune response mediated through a body fluid.
    GO:0002376    immune system process    Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
