Chapter 14
14.1 - 14.2
a foreign invader that may cause disease is called
the primary function of the lymphoid system is
the lymphoid system is composed of
all of the above (lymphatic vessels, lymph nodes, and the spleen)
pathogen
production, maintenance, and distribution of lymphocytes
the 2 collecting ducts that drain the lymphatic trunks are the
flow through lymph vessels resembles flow through
thoracic duct and right lymphatic duct
veins
lymph nodes
In general, lymphocytes (all of the above)
B and C (monitor the contents of lymph by removing debris and pathogens// act as a "check station" for cancer cells)
the region of a lymph node through which blood vessels enter and exit is called the (hilum)
are large lymphoid nodules that are located in the walls of the pharynx (tonsils)
lymphoid organs are different from lymphoid tissues in that lymphoid organs (are separated from surrounding tissues by a fibrous capsule and lymphoid tissues are not)
the white pulp of the spleen contains large numbers of (macrophages)
the spleen (all of the above)
the red pulp of the spleen is a storage site (red blood cells)
stem cells that will form T cells are modified in the (thymus)
lymph differs from plasma in that (plasma contains more protein than lymph)
lymphatic vessels that exit the lymph node are called (efferent lymphatic vessels)
lymph reenters the venous system at the (right and left subclavian veins)
lymph nodules are composed of loose connective tissue containing densely packed (lymphocytes)
the role of the spleen is slightly different than other lymph organs because it also (filters blood)
the thymus gland is positioned (just behind the sternum)
14-3
major events associated with inflammation include (redness, swelling, heat, and pain.
the body nonspecific defenses include (all of the above)
special lymphocytes that are part of the nonspecific defenses are called (NK cells)
interferon may be described as (all of the above)
virus-infected cells release (interferon)
the first line of cellular defense against pathogens (phagocytes)
which of the following contains visible granules in its cytoplasm (neutrophils)
the most active phagocytic cells found in circulating blood are (neutrophils and monocytes)
the least numerous leukocytes are (basophils)
which of the following is the LAST step in inflammation (phagocytosis)
14-4
t cells are responsible for (cellular immunity)
which of the following is a specific body defense (immunity)
the cells primarily responsible for immunity are (lymphocytes and macrophages)
in active artificial immunity (the body makes a memory of the attack)
immunity that results from antibodies ingested from breast-milk in which type of immunity (passive natural)
which of the following secretes antibodies (plasma cells)
the cells that are actively involoved in immunological surveillance are the (NK cells)
the cells responsible for humeral immunity are the (B cells)
newborn infants gain most of their immunity from (anitibodies passed from the mother across the placenta)
hum moral immunity is the responsibility of the (B cells)
blocking the antigen receptors on the surface of lymphocytes would interfere with (antigen recognition)
14.5 and 14.6
the major histocompatibilty complex (MHC) (is a membrance protein that can recognize foreign antigens

t cells are responsible for (cellar immunity)
