| A | B |
|---|
| Transportation | function of blood where oxygen/carbon dioxide, wastes, glucose are moved through body, |
| Regulation | function of blood that monitors heat, water balance, & pH (acidity) |
| Protection | function of blood that helps prevent disease |
| plasma | liquid part of blood; makes up 55% of blood |
| plasma | made up of water (90%) & proteins (10%) |
| fibrinogen | protein in plasma that helps with blood clotting |
| Albumin | protein in plasma that helps keep the water balance |
| globulins | protein in plasma that help form antibodies among other things |
| antibodies | substance that helps fight bacterial infection |
| Erythrocytes | red blood cells that carry oxygen & carbon dioxide ; live 120 days |
| hemoglobin | an iron compoundthat oxygen & carbon dioxide bonds with that causes the red color |
| anemia | condition caused by having too few red blood cells or hemoglobin |
| leukocytes | white blood cells that protect from infection & viruses |
| phagocytes | white blood cells that engulf foreign cells. |
| lymphocytes | white blood cells that produce antibodies |
| leukemia | cancer of the cells that produce wbc's which causes abnormally high wbc counts |
| platelets | fragments of cells important in blood clot formation |
| coagulation | blood clotting |
| minor break | platelets usually seal it |
| thromboplastin | an enzyme released by platelets that help with clotting |
| fibrin | end result of a major break that is formed by fibrinogen |
| anticoagulants | stop blood from clotting |
| hemophilia | genetic disorder in which the individual does not produce 1 or more of 30 clotting factors |
| stroke | blood clot in a vessel leading to the brain |
| 1st line of defense | physical barriers; sweat, saliva, skin, tears |
| 2nd line of defense | Inflammatory response; swelling, warmth; damaged cells release chemicals to increase blood flow |
| interferon | substance released to stop virus reproduction |
| 3rd line of defense | Immune response; body recognizes its own cells from pathogens |
| pathogen | disease causing agents: bacteria, viruses |
| antigen | proteins on the outside of a cell |
| lymphocytes | wbc's that recognize pathogens & produce antibodies |
| T cells & B cells | lymphocytes that complement each other & help in defense against pathogens; they remember pathogens |
| primary immune response | 1st exposure to pathogen; takes 5 days for antibody production |
| secondary immune response | repeat pathogen exposure;1-2 days for antibody production |
| active immunity | body produces own antibodies to pathogens; vaccine |
| passive immunity | antibodies from the blood of another person; temporary; from mother to baby |
| Type A blood | has A antigens; produce antibodies to B |
| Type B blood | has B antigens; produce antibodies to A |
| Type AB blood | have both A & B antigens; produces no antibodies; UNIVERSAL RECIPIENT |
| Type O blood | no antigens; makes antibodies to A & B; UNIVERSAL DONOR |
| Rh factors | an antigen present or absent on rbc's |
| Erythroblastosis | anemia in a fetus caused by an Rh- mother with a Rh+ fetus; mother's Rh+ antibodies can destroy fetal RBC's |
| HIV( human immunodeficiency virus) | virus that causes AIDS |
| AIDS | Auto Deficiency Syndrome; destroys T cells |
| Allergies | an overreaction of immune system to a normally harmless antigen |
| histamine | released by antigens which cause 1st & 2nd immune responses |
| antihistamine | antibodies found in most medications to fight allergies |
