Basic Immunology

Mature in the bone marrow and are found in the blood stream? - correct answer B - Lymphocytes Make up 1-3 % of WBC's and are increased in allergic disorders and parasite infections. - correct answer Eosinophils What waits in the tissue under the skin; engulfs invading bacterium and destroys it? - correct answer Macrophage What is the process of engulfing bacteria and taking it inside a macrophage for destruction and breakdown? - correct answer Phagocytosis Example of this immune disorder include lupus, diabetes, cancer and Allergy. Immune system attacks itself - correct answer Immune Aberration Along with the neutrophils, they also serve as the first line of defense against infection and perform the same functions as monocytes - correct answer Macrophage Examples of this immune disorder include HIV, Bruton's, and Bubble Boy Lack of an immune system - correct answer Immune Deficiency What are the secondary lymphoid organs? - correct answer -Spleen -Tonsils -Appendix -Lymph nodes Specialize in presenting parts of the organisms to other cells in the immune system, such as T cells, and are thus known as "antigen presenting cells" - correct answer Monocytes

These lymphocytes mature in the Thymus and are responsible for cell mediated immunity? - correct answer T-Lymphocytes What are the types of T-cells - correct answer -Killer T cells -Helper T cells -Regulatory T cells The _____ Immune system is the system that is always ready and does not need to depend upon specific recognition. - correct answer The Innate Immune System How many T-cells are there? - correct answer 3 What are the two types of immune systems? - correct answer -Innate Immune System -Adaptive Immune System Examples of this type of immune disorder include Lukemia and Lymphoma. Immune system is overactive and cannot shut down. - correct answer Immune Proliferation The __ System is made up of a number of proteins that circulate in the body and are harmless until they are activated and attach to bacteria. Once they attach they either punch holes in the cell membrane or make it easier for the phagocytic cells to engulf and destroy the cell. - correct answer Complement How many classes of antibodies are there? - correct answer 5 In order for the Immune System to do its job it must be able to do what two things? - correct answer -Recognize "self" from "non-self" -Know what's dangerous and what's not

What are the two types of immunity? - correct answer -Active -Passive What makes up 20%-25% of the total WBC and are very important because they provide immunologic "memory"? - correct answer Lymphocytes WBC found in very small numbers in circulating blood and nasal secretions. - correct answer Basophils With this type of immunity, you are given the immunity response from mother to child or from blood transfusion. - correct answer Passive Immunity How long do Macrophages stay in the blood stream before patrolling the body's tissues? - correct answer 3 days Once a T-cell becomes excited and multiplies it goes through a process called what?? - correct answer Colonal Expansion How many proteins is a T-cell designed to recognize? - correct answer One Which type of T-cell kills abnormal host cells? - correct answer Killer T-cells or Cytotoxic T-cells What type of T-cell directs the Immune response by sending out various signals which help other cells get excited about defending the body? - correct answer Helper T-cells Which Immune System is the body's first line of defense against infection? - correct answer Innate Immune System Which antibody created by the B-cell is the first antibody produced? - correct answer IgM

With this type of immunity, you make the immune response through vaccination or exposure. - correct answer Active Immunity When an allergen binds to and cross-links the IgE, the ___ releases chemical mediators from its granules

• correct answer Mast Cell Where are neutrophils developed? - correct answer Bone Marrow What signals other immune cells that there is a battle going on and attracts other "professional Phagocytes" from blood to infected tissue to help out? - correct answer Cytokines What are the 5 classes of antibodies? - correct answer -IgG -IgA -IgM -IgE -IgD What migrates to the site of infection within a few hours of the entry of microbes? - correct answer Neutrophils Make up 60 - 70% of WBC and are part of the organism's first line of defense against infection. - correct answer Neutrophils What proteins are always in the blood? - correct answer Compliment proteins? When macrophages eat, they make signaling proteins that are called what? - correct answer Cytokines What components make up the Innate Immune System? - correct answer - Physical and Chemical Barriers (Such as the Skin) -Phagocytic Cells

-Blood Proteins (Complement proteins) -Cytokines What term means to "prepare for eating"? - correct answer Opsonization Blood contains three major types of cells that float in the liquid plasma. What are they? - correct answer -Red Blood Cells -White Blood Cells -Platelets What are the primary Lymphoid Organs - correct answer -Bone Marrow -Thymus Which antibody created by the B-cell is found in the highest quantities in the blood stream? - correct answer IgG Which antibody created by the B-cell is the allergic antibody? - correct answer IgE
