      2. Predates the evolution of the more specific Immunity provided by antibodies and Lymphocytes
    3. Adaptive Immunity
      1. Organism specific Immunity that relies on prior "memory" of exposure
      2. Immune System evolved beyond the more primitive Innate Immunity

    5. Lysosome (and Lysozyme)
      1. Lysozyme-containing vacuoles produced in cellular golgi apparatus
      2. Lysomsomes fuse with Phagosomes, resulting in pathogen lysis (esp. Bacterial cell walls)

Immunity, Innate (C0020969)

Definition (MSH) The capacity of a normal organism to remain unaffected by microorganisms and their toxins. It results from the presence of naturally occurring ANTI-INFECTIVE AGENTS, constitutional factors such as BODY TEMPERATURE and immediate acting immune cells such as NATURAL KILLER CELLS.
Definition (GO) Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. [GO_REF:0000022, GOC:add, GOC:ebc, GOC:mtg_15nov05, GOC:mtg_sensu]

Definition (PSY) Medical science dealing with the study of immunity. Used for the scientific discipline or the immunological processes themselves.
Definition (CSP) branch of biomedical science concerned with the response of the organism to antigenic challenge, the recognition of self and foreign substances, and the biological, serological and physical chemical aspects of immune phenomena.

Adaptive Immunity (C0678209)

Definition (MSH) Protection from an infectious disease agent that is mediated by B- and T- LYMPHOCYTES following exposure to specific antigen, and characterized by IMMUNOLOGIC MEMORY. It can result from either previous infection with that agent or vaccination (IMMUNITY, ACTIVE), or transfer of antibody or lymphocytes from an immune donor (IMMUNIZATION, PASSIVE).
