|---|
| Plasma | Contains proteins, antibodies, hormones, and enzymes |
| Red Blood Cells | Also known as erythrocytes |
| Red Blood Cells | Transports oxygen from lungs to body tissue (cells) |
| Red Blood Cells | Contain hemoglobin |
| Hemoglobin | An iron-containing protein in red blood cells in which oxygen binds to |
| Oxyhemoglobin | When oxygen binds to hemoglobin |
| White Blood Cells | Also known as Leukocytes |
| White Blood Cells | Main purpose is to fight off disease |
| Phagocytes | Engulf and destroy bacteria at the site of infection by the process of phagocytosis |
| Lymphocytes | Produce antibodies, which act against foreign molecules known as antigens |
| Immune response | An antigen-antibody reaction |
| Platelets | Play a key role in blood clot formation |
| Active Immunity | Results when antibodies are produced by the body in response to a foreign substance (antigen) in the body |
| Passive Immunity | Develops when an individual receives antibodies from an outside source (medication) |
| Vaccinations | A weakened strand of the virus is used to stimulate the immune system |
| Antibiotics | Chemicals produced outside the human body, usually by fungi, that can be given to a person to kill the bacteria causing an infection |
| B-cells | Respond to specific antigens by producing antibodies that will bind only to the antigen |
| Memory B-cells | Remain in the body in case you encounter the same invading microorganism again |
| Killer T-cells | Seek and destroy infected body cells with the virus in it |
| Helper T-cells | Assist both B-cells and Killer T-cells |
| Allergic Reactions | Results from the over activity of the immune system to common substances such as dust, mold, pollen, or certain foods |
| Autoimmune Diseases | Results from when the immune system begins to attack normal body tissue |
| AIDS | Develops when the HIV virus destroys the Helper T-cells and the body is no longer able to protect itself from diseases that may attack it |
| Anemia | A condition in which blood cannot carry sufficient amounts of oxygen to body cells |
| Leukemia | A form of cancer in which the bone marrow produces non-functional white blood cells |
| Transfusion | When a person receives blood from an outside source |
| Blood Type O | Universal donor |
| Blood Type AB | Universal recipient |
