Human Immune System
| Question | Answer |
|---|---|
| What immune system repels invading antigens indiscriminately, but cannot prevent disease entirely? | Non-specific immune system. |
| What immune system creates immune responses targeted at specific disease-causing antigens? | Specific immune system. |
| What type of protein, also known as immunoglobulin, binds to specific antigens to destroy or deactivate them? | Antibody |
| What are antibodies created by? | B-lymphocytes |
| When are antibodies released? | When a particular antigen is present. |
| What is molecularly coded to attack one and only one antigen? | Antibody |
| What specific immune response is the process in which antibodies produced by B-cells can destroy or deactive an antigen without the presence of a B-cell? | Humoral |
| What specific immune response is the process in which a cytotoxic or killer, T cell must be bound to a harmful antigen to destroy it? | Cell-mediated |
| What chemical messengers are released when an infection is present, and regulate the body's immune response? | Cytokines |
| A cluster of immunoglobulin molecules that distinguish cells of our body from those that are not is called what? | Major Histocompatability Complex |
| What is a product of the non-specific immune system, and is triggered when granulocytes release histamines? | Inflammatory response |
| What does the Inflammatory response do? | Increases blood flow to the infected area and attracts other white cells to fight the infection. |
| What is any substance capable of triggering an immune response? | Antigen |
| A killed or weakened form of a specific antigen injected into the body is called a what? | Vaccination |
| What is an antibody-producing white cell of the specific immune system? | B-Cell or B-Lymphocyte |
| What is a white cell that controls the nature and extent of all our immune responses? | Helper T-Cell or T-Lymphocyte |
| What cell is responsible for destroying infected, or abnormal, cells of our own body, such as cancer cells? | Cytotoxic, or Killer T-Cell |
| What diseases are caused when the cells of the immune system mistakenly attack healthy cells of the body? | Autoimmune diseases |
| Where is the origin of all blood cells? | Bone marrow |
| What are the white cells involved in the non-specific immune response, that contain granules of powerful chemicals that are released in the presence of a harmful antigen? | Granulocytes |
| What are the protein molecules, also called antibodies, that identify cells of the body, distinguishing them from those that are not? | Immunoglobulins |
| What is the name for white blood cells of all types? | Leukocytes |
| What system is composed of vessels, nodes, and a fluid called lymph, that also serves as a conduit for the cells of the immune system to do their work? | Lymphatic system |
| The lymphatic system bathes cells in what? To flush out harmful antigens? | Lymph |
| What white cells are involved in the specific immune response? There are two types: B-Cells and T-Cells. | Lymphocytes |
| What white cells surround and engulf foreign antigens and clean up cellular debris? Also referred to as "antigen-presenting cells" because they present foreign antigens to other cells of the immune system. | Macrophages |
| What is a white cell of the non-specific immune system that will eventually develop into a macrophage? | Monocyte |
| What body organ filters the blood for harmful antigens, produces B-cells and T-cells, and stores macrophages and red blood cells? | Spleen |
| What are the cells of the bone marrow that are capable of developing into any type of blood cell called? | Stem cells |
| Name the organ of the immune sytem where T-lymphocytes develop? It becomes non-functional as one moves into adulthood. | Thymus |
