| Leukemia | Cancer in the blood cells that grow in the bone marrow and found in large numbers in the bloodstream |
| immune system | a network of cells, tissues, and organs that work together to defend the body against attacks by "foreign" organisms |
| Foreign organisms | bacteria, fungi, parasites and viruses. |
| Pathogens | organisms that cause disease |
| antigen | a foreign substance that stimulates the immune system to attack |
| immune response | how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful |
| lymphocytes | white blood cells, they form antibodies that make it easier for the immune system to fight the foreign organisms |
| allergens | substances that can cause the body to react |
| Allergies | inappropriate immune responses to substances that are usually harmless |
| Immune deficiency diseases | disorders in which your resistance to disease becomes dangerously low |
| Autoimmune disease | diseases causing your immune system to attack your own body's cells and tissues by mistake |
| Hives | red and itchy bumps on your skin caused most commonly by allergic reactions to foods, medicines, latex and internal disease |

| HIV | Human immunodeficiency virus, a virus that kills or damages cells of the body's immune system |

| Cryoprecipitate | a concentrated source of certain plasma proteins. It is used to treat some bleeding problems. |
| red blood cells | These carry oxygen from the lungs to other parts of the body and then they carry carbon dioxide back to the lungs. A low count is called anemia. A transfusion may be needed to treat anemia |
| White blood cells | These help fight infection, bacteria and other substances that enter the body. When the count becomes too low, it is called Neutropenia. |
| Platelets | These help blood to clot. Platelet transfusions are given when the platelet count is too low |
| Transfusion | the process of giving blood products through an intravenous (IV) catheter. |
| Crossmatching | Taking a sample of blood to find the type and match it with the donor blood in order to decrease the chance of a reaction |
| Leuko | white |
| emia | blood |
| leukemia | the formation of abnormal white blood cells in the blood |
| leukemia cells | abnormal white blood cells which don't die when they should and crowd out normal blood cells |
