WITH QUESTIONS AND ANSWERS
_______ are a type of preparation that produce artificially acquired active immunity against the injected
substance -- vaccines
-a _________ cell is differentiated B cell which functions to produce and secrete antibodies -- plasma
-a hypersensitive reaction to a non-harmful substance is also called a(n) -- allergy
-A(n)__________ is the cell type responsible for phagocytizing debris and foreign particles from the
blood within the splenic sinuses -- macrophage
-activates complement; responds to bacteria, viruses, and toxins -- IgG
-an abnormal elevation in body temp is called -- fever
-any large molecule capable of triggering an immune response is called an -- antigen
-as a part of the innate defenses, many pathogens that are ingested are destroyed by _______ within
the stomach -- acids
-auto- -- self
-B cell activation -- IgD
-bacteria, protozoa, viruses and fungi sometimes cause disease. Therefore, they are classified as --
pathogens
-cell-mediated immunity is a specific defense mediated mainly by ______ lymphocytes, which interact
directly with antigen-presenting cells -- T
-cells derived from monocytes that function as phagocytes and antigen-presenting cells are called --
macrophages
-class I MHC's are found on all cell types except -- RBC's
-clusters of lymph nodules found within the mucosa of the distal small intestine are called -- Peyer's
patches
-colloid osmotic pressure within the capillaries is created by the presence of plasma______ and is
responsible for drawing most of the tissue fluid back into the capillaries -- proteins
-cytotoxic T lymphocytes bind to ______ and release perforin to destroy them -- tumor cells, viral-
infected cells
, -Defends against bacteria and viruses, found in secretions -- IgA
-describe phagocytosis -- a process where foreign particles are engulfed by a cell
-Excess tissue fluid resulting from the failure of proper lymphatic drainage is called -- edema
-fluid in order beginning with the blood in the blood capillaries -- 1. blood capillaries (blood)
2. interstitial spaces (interstitial fluid)
3. Lymphatic capillaries (lymph)
4. Lymphatic vessels (lymph)
5. lymphatic ducts (lymph)
6. subclavian veins (blood)
-following cloning, some B cells differentiate into ________ B cells, which can rapidly respond to a future
exposure to the same antigen. -- memory
-functions of the lymph node -- filtration of lymph, site of B and T cell activation
-Human immunodeficiency virus (HIV) causes: -- AIDS
-humor- -- moisture, fluid
-hydrostatic pressure forces fluid from the tissues into the lymphatic capillaries, where it is called --
lymph
-identify examples of antigen-presenting cells -- dendritic cells, B cells, macrophages
-identify the largest type of lymphatic vessels, which deposit lymph into subclavian veins -- collecting
ducts
-identify three age-related changes in the immune system: -- the number of T cells diminish only slightly,
although the response time declines, decline begins early in life, due in part to shrinkage of the thymus,
with age, proportions of antibodies in different classes change (IgA and IgG increase, IgM and IgE
decrease).
-identify three substances transported through the lymphatic system in lymph -- lymphocytes and
macrophages, dietary fat absorbed from intestines, bacteria and viruses
-immun- -- free, exempt
-immune responses that protect against many types of pathogens are referred to as -- nonspecific
defenses
-In autoimmune disorders, the immune system mistakenly attacks -- "self" antigens
-in immune system disorders known as __________ disorders, the immune system can not tolerate self-
antigens, attacking antigens that are not foreign. -- autoimmune
