Definition
These cells rhythmically produce action potentials that spread through the muscle fibers of the atria. The resulting contraction pushes blood into the ventricles.
Term
connection between atria and ventricles
Definition
The only electrical connection between the atria and the ventricles is via the atrioventricular (AV) node. The action potential spreads slowly through the AV node, thus allowing atrial contraction to contribute to ventricular filling, and then rapidly through the AV bundle and Purkinje fibers to excite both ventricles.

Term
cell mediated immune response
Definition
is completed by T lymphocytes through two methods, they can either directly attack and destroy the invader or they can indirectly lead to the antigens death by enabling other lymphocytes.
Term
humoral immune response
Definition
is provided by antibodies that circulate in the body fluids that bind, inactivate and mark invaders for destruction by macrophages.
Term
complement system
Definition
works to assist the antibodies and phagocytic cells to clear pathogens from an organism by removing the antigen and antibody complexes and preparing the membrane attack complex
Term
why hemolytic plaque assay use spleen
Definition
because the spleen is where the B cells rapidly divide. The Hemolytic plaque assay can enumerate the B-cells, which secrete the antibodies. The spleen is where a response will be shown after introducing the antigen due to the antibodies from the B cells.
Term
direct ELISA
Definition
then poured into the well. The viral protin on the cell surface will bind to the primary antibody if it is a match. Then, primary antibody is added again, followed by secondary antibody HRP. Then ABTS is added to produce a colored product in a positive response.
Term
hybridoma cells
Definition
B cells harvested from a host animal's spleen and fused with cancerous myeloma cells. This new cell will possess properties from both cells. It is a perpetually regenerating cell line that produces a specific antibody that is used for identifying presence of proteins, viruses, etc. It also is the basis of "Magic-bullet" therapy.

where antibodies are created that are selective for cancerous cells. These antibodies are bound to special toxins with the intent of poisoning ONLY the cancerous cells.

Term
lymph nodes
Definition
Numerous lymph "nodes" are clustered along the lymphatic vessels in areas such as the axilla, groin, and neck. In the nodes, the lymph is filtered to remove debris, microorganisms, etc. If an antigen is encountered, the lymphocytes in the nodes assist in activating the immune response (see below).
Term
macrophages
Definition
(phagocytes) are large, mobile cells derived from monocytes (a type of agranular white blood cell). They are commonly found in loose connective tissue, bone marrow, and lymphoid tissues where they freely move about, engulfing dead tissue and foreign matter (including bacteria)
Term
lymphocytes
Definition
are another class of specialized white blood cells (also agranulocytes) which are most abundant in the lymphoid tissues. They initially develop in the bone marrow, and then migrate to become immunocompetent. Two classes exist, T lymphocytes (T cells), which migrate to the thymus, and B lymphocytes (B cells)
Term
anitgens can be
Definition
be bacterial, viral, or particulate matter, living or non-living, hence any substance that is detected as foreign by the organism.
Term
antibodies are
Definition
special class of proteins that are produced by plasma cells (daughter cells of activated B lymphocytes).
Term
polyclonal antibodies produced by
Definition
injecting a host animal with a specific antigen that result in producing multiple clonal antibodies that are capable recognize the same antigen
Term
monoclonal antibodies produced by
Definition
by injecting the host animal with a specific antigen and then culture the same clonal antibodies that released by the plasma cells derived from the same mother B cells. Due to their unique specificity, monoclonal antibodies have become a common tool in research and medical testing. B-cells are harvested from the host animal’s spleen and fused under special laboratory conditions with cancerous myeloma cells. The resulting cell, called a hybridoma
