an example of an autoimmune disorder | rheumatoid arthritis |
undesirable response to pollen,animals or food is an | allergy |
the body's first line of defense when facing antigens | barriers |
three types of barriers | anatomic;biochemical;mechanical |
example of anatomic barrier | skin;mucous membranes;intestinal tract |
examples of biochemical barriers | tears;sweat;sebacious glands |
examples of mechanical barriers | coughing;urination;dead cells slough off |
2nd line of defense against infection | inflammation process |
inflammation process results in | skin that is red, swollen and warm to touch |
3rd line of deense against infection | antibody defense |
all blood cells originate in the | bone marrow |
organs of the immune system | bone marrow;thymus;lymph nodes;spleen;tonsils;adnoids;appendix;peyer patches |
intercept antigens from invading the upper respiratory tract | tonsils and adnoids |
fight antigens that reach the blood stream | bone marrow and spleen |
WBC's with immunity functions | lymphocytes |
B lymphocytes produce | antibodies |
B lymphocytes make up abou _____ of the total lymphocytes | 20% |
Act directly on target cells and provide cell mediated immunity | T cells |
T cells make up _____ of the total lymphocytes | 80% |
4 types of T cells | helper;suppressor;memory;killer |
produce protein called lymphokines that help othr lymphocytes and phagocytes perform their functions | T helper cels |
can directly kill infected or malignant cells | killer T cells |
antibodies from the B cells are known as | immunoglobulins |
the 5 classes of immunoglobulins are | IgA;IgD;IgM;IgG;IgE |
the body hs the most of what immunoglobulin | IgG |

the spread of a tumor to a new site is called | metastasis |
cancer arising from the epithelial tissue | carcinomas |
cancer arising from connective tissue | sarcoma |

cancer of the lymph tissue | lymphomas |
cancer of the cartilage | chondrosarcoma |
new frowth eithr benign or malignant | neoplasm |
tumors that are slow growing,do not invade other tissue, do not spread are referred to as | benign |
