Chapter 13 The Immune Response and Lymph+atic system
| Question | Answer |
|---|---|
| Self-antigens are coded by a group of genes located on chromosome | Six and form the MHC |
| The antibody found in body secretion is | IgA |
| An antibody is | A protein produced by plasma cells |
| Which of the following cell types secretes antibodies? | Plasma cells |
| Which of the following provide defense against vial infections? | Interferons |
| Which of the following cells is a granulocyte? | Basophil |
| Immunity that is a result of an actual infection is called | Naturally acquired active immunity |
| Acquired | Disease |
| Passive | Antibodies |
| A substance capable of raising the body temperature is | Pyrogen |
| When an organ or tissue is transplanted between genetically different individuals it is called | Allograft |
| Which of the following is a systemic autoimmune disease? | Rheumatoid athritis |
| Which of the following is part of the second line of defense? | Phagocytosis, Fever, and PH of the skin |
| Cells infected with a virus produce glycoproteins that interfere with viral replication and impede its spread; these glycoproteins are called | Interfereons |
| The first line of defense that prevents microbes from entering the body includes | Skin |
| T cells ( T lymphocytes) are divided into four categories | Killer T cells, Helper T cells, Suppressor T cells, and Memory T cells |
| What is a pentamer and the largest of the immunoglobulins? | IgM |
| The category of immunoglobulins that can also be found in colostrum and mother's milk is | IgA |
| GALT is an example of a collection of lymphatic nodules in the | Small intestine |
| Which of the following organs break down worn- out red blood cells? | Spleen |
| Enzymes that attack the peptidoglycan layer of bacteria and are present in perspiration, nasal secretions, saliva, and tears are | Lysozymes |
| Delayed hypersensitivity is a result of | Cell- mediated immune reactions |
| B cells are responsible for | Antibody - mediated immunity |
| Substances that stimulate the production of antibodies are called | Immunagens |
| The body's decreased ability to fight infection is called | Immunosuppression |
| The category of immunoglobulins that is implicated in allergic reactions | IgE |
| Granulocytes are subdivided into three groups | Basophils, Eosinophils. and Neutrophils |
| Large, circulating phagocytic agranulocytes that develop into marcophages as they leave the blood vessels are called | Monocytes |
| Strong immune response to a substance that is usually not harmful to the body but causes hypersensitivity reactions | Allergys |
| Occurs when the immune system is unable to distinguish between self and non-self antigens and attacks the cell of the body | Autoimmunity |
| Cross the placenta | IgG |
| Found in tears, salvia | IgA |
| Pentamer | IgM |
| Allergic reactions | IgE |
| Monomer bound to surface of B cells | IgD |
