front 1 Neutrophils | back 1 Phagocytize and digest pathogens |
front 2 Monocytes | back 2 Mature into macrophages and engulf pathogens |
front 3 Macrophages | back 3 Phagocytize pathogens and debris, present antigens to T cells |
front 4 Dendritic Cells | back 4 Capture and present antigens to T cells, important in initiating immune responses |
front 5 Eosinophils | back 5 Involved in the defense against parasites and allergic reactions |
front 6 White Blood Cells | back 6 Neutrophils, Monocytes, Macrophages, Dendritic Cell, Eosinophils |
front 7 Lymphocytes | back 7 Helper T Cells, Cytotoxic T cells, Regulatory T cells, Memory cells, Plasma cells, NK cells |
front 8 Helper T Cells (CD4+ T Cells) | back 8 Coordinate immune responses, activate B cells and cytotoxic T cells |
front 9 Cytotoxic T Cells (CD8+ T Cells) | back 9 Destroy infected or abnormal cells |
front 10 Regulatory T Cells (Tregs) | back 10 Suppress immune responses to prevent excessive reactions |
front 11 Plasma Cells | back 11 Produce antibodies (immunoglobulins) that neutralize pathogens |
front 12 Memory B Cells | back 12 "Remember" previous encounters with pathogens for a faster response upon re-exposure |
front 13 Natural Killer (NK) Cells | back 13 Recognize and destroy virus-infected cells and cancer cells |
front 14 Granulocytes: | back 14 Basophils, Mast Cells |
front 15 Basophils | back 15 Release histamine and other mediators involved in allergic reactions |
front 16 Mast Cells | back 16 Release histamine and other inflammatory substances in response to allergens |
front 17 Phagocytes | back 17 Various cells, including neutrophils, monocytes, macrophages, and dendritic cells, are involved in phagocytosis—engulfing and digesting pathogens |
front 18 Antigen-Presenting Cells (APCs) | back 18 Dendritic cells, macrophages, and B cells present antigens to T cells to initiate immune responses. |
front 19 MHC Class | back 19 Present endogenous antigens to cytotoxic T cells |
front 20 MHC Class II | back 20 Present exogenous antigens to helper T cells |
front 21 Cytokines | back 21 Small proteins that act as signaling molecules between immune cells |
front 22 Antigens | back 22 Antigens are molecules (often proteins or polysaccharides) that can trigger an immune response |
front 23 Antibodies (Immunoglobulins): . | back 23 bind to specific antigens, marking them for destruction or neutralization. They play a crucial role in humoral immunity |
front 24 Complement System | back 24 A group of proteins that enhance the immune response by promoting phagocytosis, attracting immune cells, and forming membrane attack complexes to destroy pathogen. |
front 25 Humoral Immunity | back 25 A component of the adaptive immune system that involves the production of antibodies by B cells. These antibodies circulate in the bloodstream and other bodily fluids, targeting and neutralizing pathogens such as bacteria and viruses. |
front 26 Innate Immunity | back 26 The first line of defense in the immune system that provides immediate, non-specific protection against a wide range of pathogens. It includes physical and chemical barriers, as well as cellular components such as phagocytes and natural killer cells. |
front 27 Passive Immunity | back 27 Immunity is acquired through the transfer of pre-formed antibodies from one individual to another |
front 28 Active Immunity | back 28 Immunity is developed by the body's Immune system in response to exposure to a pathogen or through vaccination |
