Immunology (test 1) immune system
Process of being protected against foreign antigens ✔✔immunity
Aka immunoglobins, these are specific glycoproteins found in serum or plasma produced by B-lymphs
when body detects harmful substances called antigens ✔✔antibodies
Aka immunogens, these large molecules found on surface of cells, viruses, fungi, bacteria, pollen,
chemicals, foreign particles causing body to produce antibodies against it; can be formed in the body
with bacterial toxins or tissue cells ✔✔antigens
Portions or fragments of an antigen that REACT with antibodies and lymph receptors ✔✔epitope
Very small molecules that can bind to a larger carrier molecule and behave as an antigen ✔✔hapten
Molecule that when coupled with a hapten, renders the hapten immunogenic ✔✔carrier
Main function is to recognize microbes as being either self or nonself ✔✔immune system
Defense, homeostasis, surveillance ✔✔3 functions of immune system
First line of defense, natural (innate) immunity, acquired (adaptive) immunity ✔✔3 types of immune
response
Defense mechanism that body uses immediately after exposure to a microbe; it is non-specific and
nonadaptive ✔✔natural immunity
Components include phagocytic cells along with mast cells, neutros and macrophages ✔✔cellular
component
Components include complement proteins, lysozymes, interferons ✔✔humoral components
Proteins that produce inflammatory effects and destroy cells when activated ✔✔complement proteins
Enzyme secreted by macrophages that attack cell walls of some bacteria ✔✔lysozymes
Proteins produced by many cells in response to viral infections to BLOCK replication of virus in other
cells ✔✔interferons
Immunity that becomes operational when natural immunity is overwhelmed; it is antigen-specific
✔✔adaptive immunity (acquired)
