| WBC aka | leukocytes |
| WBC produced in | bone marrow |
| stem cells | initally all blood cells are nospecific |
| lymphocytes | either T-cell or B-cell |
| T-cells | made in marrow, to thymus |
| T-cell either become | regulator T-cells or Effector T-cells |
| Regulator T-cells made of | helper and suppressor cells |
| Effector T cells | killer cells aka cytotoxic |
| Helper T cells purpose | help fight infection |
| antibodies | chemical substances that destory foreign agents |
| B-cell lymphocytes | mature in bm and migrate to spleen |
| plasma cells produce | antibodies |
| formation of antibodies called | humoral response |
| memory cells | convert to plasma - accumulate in lymph and produce swelling |
| neutrophils and monocytes are | phagocytes |
| neutrophils aka | microphages - because they are small |
| lymphoid tissue | thymusgland, tonsils, adenoids, slpeen |
| tonsils and adenoids job | filter bacteria from tissue fluid |
| spleen's job | both hematopoietic and immune function |
| lymph nodes | similar to capillaries that drain tissue fliud |
| B-Cells are either | plasma or memory |
| phagocytes aka (3) | neutrophils, monocytes, microphages |
| natural killer cells | lymphocyte like - move around body looking for virus to kill |
| immunoglobolins aka | antibodies |
| interferons | chemicals that primarily protect cells from viral |
| anergy | inability to mount an immune response |
