Blood and Immunity
Study your blood/immunity vocabulary
| Question | Answer |
|---|---|
| Solid components of blood | white blood cells, red blood cells, and platelets; 45% |
| Liquid component of blood | Plasma, 55% |
| transports oxygen to cells and picks up carbon dioxide for removal | red blood cell function |
| red, biconcave disk, no nucleus | structure of a red blood cell |
| iron containing pigment that gives rbcs their red color and helps attach oxygen | hemoglobin |
| cells that help with the immune response by eating foreign invaders or producing antibodies | function of white blood cells |
| large, has nucleus, can carry out amoeboid movement | structure of white blood cells |
| very small cells with the capability of clotting blood | platelets |
| enzyme controlled reactions that occur when platelets rupture and blood proteins prevent bleeding | blood clotting |
| location of blood cell production | bone marrow |
| failure of homeostasis | disease |
| foreign invaders such as a virus, bacteria, fungus, or parasite that can cause disease | pathogen |
| protective function of the blood that attacks foreign invaders | immune system |
| physical and chemical barriers such as skin, sweat, tears, stomach acid, etc. | first line defense |
| identifying markers found on most cells that help the immune system differentiate between "Self" and "non-self" cells | antigens |
| a cell engulfs another large object, cell, or organism | phagocytosis |
| y-shaped proteins specific to an antigen. Marks the cells with the matching antigens for destruction | antibody |
| another name for disease causing organisms | microbes |
| white blood cells attack | second line of defense |
| true immunity; pathogens are remembered and attacked immediately if they reenter the body | third line of defense |
| the production of cells or antibodies in an attempt to destroy foreign invaders in the body | immune response |
| drug that treat bacterial diseases; not effective against viruses | antibiotics |
| body makes its own antibodies to attack an antigen; results from having the disease or use of vaccine | active immunity |
| dead or weakened pathogen that is taken in by the body so that it builds antibodies or attacking WBCs to build immunity | vaccine |
| borrowed immunity; taking antibodies from another person or animal; mothers pass antibodies to their babies during development | passive immunity |
| antigens found on red blood cells that give a person the designation "+" or "-" | Rh factor |
| determined by antibodies in recipient's blood; incompatible blood will be fought by the immune system | transfusion |
| slows down a person's immune system so that they may receive an organ transplant | immunosuppressant drugs |
| universal donor because it has no antigens for other blood types to attack | O blood (O- specifically) |
| universal recipient because it has no antibodies to attack the antigens on donated blood | AB blood (AB+ specifically) |
| virus that attacks the immune system (helper T cells) and the infected individual cannot fight simple diseases | HIV/AIDS |
| low oxygen levels due to low blood count, misshapen rbsc, or ineffective hemoglobin/iron levels | anemia |
| bone marrow cancer; produces non-functioning white blood cells | leukemia |
| inability to clot blood | hemophilia |
| body attacks harmless antigens and triggers the immune response; still specific to an antibody/antigen reaction | allergies |
| body attacks itself; a structure, organ, or tissue is seen as a foreign invader | autoimmune diseases |
