|---|
| infection | invasion by a pathogen or foreign body |
| immune system | a body system composed of cells and their products that interact to protect the individual against threats from foreing cells or materials. |
| disease | The consequence of infection, inherent weakness or stress which hurts normal phsyiological functions |
| antigen | foreign body that causes an immune response. |
| non-specific immune response | physical and biochemical barrriers.(skin, mucus, nose hairs, phagocytosis, inflammation.) |
| phagocytosis | cell engulfs material and encloses it in a vacoule in the cytosol. |
| specific immune response | antibodies, lymphcytes. |
| antibodies | a blood protein made in response to an antigen, they combine. |
| lymphocytes | a small wbc important in the immune response. |
| inflammation | swelling in response to tissue damage and foreign objects |
| cell-mediated response | killer T-cells attack and destroy infected cells and other sells of the body that have become abnormal.(cancer cells) |
| antibody-mediated cells | B cells porduce antibodies which mark them for destruction by nonspecific defenses. |
| immunity | resistance |
| vaccines | meds that induce specific immunity w/out causing the disease. |
| clonal selection | a porcess where only antibodies able to bind with specificantigens are selected to divide |
| primary immune response | the first response to an antigen |
| secondary immune response | happens when an animal encounters the same antigen later-faster, greater magnitude and longer than primary immune response |
| complement system | a complex group of serum proteins that canndestroy antigens |
| HLA | human leukocyte antigens- the self-proteins that Tcells recognize |
| tolerance | the ability to survive a condition. Failure of T cells to react against self HLA. |
| autoimmuntiy | a disorder in which antibodies are produced against own of the body's own cells. |
