the basics of Humoral Immunity mediated by B Cells, B cells produce antibodies, first response is slow compared to subsequent exposure,
Cell-Mediated Immunity characterized by the dominant role of small T cells, Primary defense against intracellular organisms
Mechanism of action r/t Cell-Mediated Immunity T cells produce lymphokines Lymphokines attract macrophages and neutrophils to the site for phagocytosis, or cytotoxic killer T cells can respond directly
what are some things we have to look forward to r/t getting older r/t our immune system? High incidence of tumors, Greater susceptibility to infections, Delayed hypersensitivity response is decreased, decreased movement of respiratory secretions
what are some things we have to look forward to r/t getting older r/t our immune system?...as if that wasn't enough... Decreased production of saliva and gastric secretions Decreased tear production increases risk of eye inflammation and infection Structural changes in urinary system leads to urinary retention or stasis s/s of infection are more subtle
