DEFINITION 5 produced in bone marrow eventually migrate to peripheral organs
TERM 6
B-Lymphocytes
DEFINITION 6 Turn into plasma cells when activated (which produce antibodies) TERM 7
Mononuclear Phagocytes
DEFINITION 7 Responsible for capturing, processing, and presenting the antigen to the lymphocytes TERM 8
Humoral Immunity
DEFINITION 8 The Humoral Immune Response (HIR) is the aspect of immunity that is mediated by secreted antibodies (as opposed to cell-mediated immunity, which involves T lymphocytes) produced in the cells of the B lymphocyte lineage (B cell). TERM 9
Cell-Mediated Immunity
DEFINITION 9 Cell-mediated immunity is an immune response that does not involve antibodies or complement but rather involves the activation of macrophages, natural killer cells (NK), antigen- specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
