Immune System
| Term | Definition |
|---|---|
| Immune System | enables the body to fight off infection and pathogens. |
| Skin | surrounds and protects the entire body, physically blocks invading pathogens |
| Mucus membrane | use hairlike cilia and sticky liquid to trap pathogens trying to enter the body |
| Circulatory System | coordinates attacks on pathogens that manage to enter the body |
| Basophil and Mast cells | are white blood cells that release chemical signals that attract other white cells to the site of an infection. |
| Eosinophils | are white blood cells that help rid the body of parasites by injecting them with toxic substances |
| antibodies | help fight infection by binding to a pathogen’s membrane proteins, clumping pathogen cells so they can be engulfed by phagocytes, or activating proteins that weaken the pathogen’s cell membrane. |
| passive immunity | a type of immunity that prevents infection without an immune response. |
| inherited immunity | Immunity passed from mother to infant is a type of passive immunity. |
| active immunity | Immunity that requires a response from your own body’s immune system . |
| T cells | destroy body cells that have already been invaded by a pathogen. |
| B cells | produce proteins that can inactivate a pathogen before it invades any body cells. |
| phagocytes | is a white blood cell that engulfs pathogens. |
| interferons | are infection-fighting proteins produced by cells that have been invaded by a virus |
| specific immune response | is an immune response that occurs on the level of the cell and is slightly different for each type of pathogen |
| nonspecific immune response | is an immune response that is the same no matter what the pathogen is, and includes inflammation and fever. |
| inflammation | its main characteristics are swelling, redness, pain, itching, increased warmth at the site of an infection and it helps bring white blood cells to the infected site |
| fever | its main characteristics is body temperature rises. it stimulates interferon production and increases rate of white blood cell production |
| Antigens | are protein markers that help the immune system tell the difference between a normal body cell and a pathogen |
| memory cells | are required by Acquired immunity which recognize antigens that have previously invaded your body. |
| cellular immunity | is a type of acquired immunity that depends on activated T cells. |
| humoral immunity | is a type of acquired immunity that depends on antibodies. |
| tissue rejection | it can be prevented when donors and recipients of transplant tissues should have similar protein markers on their cells. |
| suppress | An organ recipient takes drugs that the immune system. |
| vaccine | stimulates the body to produce memory cells without causing illness. |
| antiseptic | is a chemical that kills pathogens before they enter the body. |
| antibiotic resistant | bacterium is a pathogen that is no longer affected by a medicine that was once used to treat it. |
