When B-cells are activated, they make _____ cells which secrete antibodies.
_______ are the molecular configurations (usually proteins) on pathogens that are recognized and bound by aspects of the specific immune system. They are usually associated with cell membranes of invading organisms.
_______ T-cells destroy infected cells by lysis.
Means "big eater" - large phagocytic cell derived from monocytes. important in the non-specific defense and as antigen presenters in the specific immunity.
Systemic lupus and rheumatoid arthritis are examples of _______ diseases.
Type of white blood cell important in attaching large, multicellular, invaders (e.g. worms) by releasing enzymes that attack their outer coverings.
Memory cells are importnat in the _______ immune response which happens when a person is exposed to a pathogen he/she has encoutnered previously.
B-cells and T-cells are examples of _________.
The _____ region of an antibody is unique, and responsible for recognizing and binding specific antigens.
Histamine causes ________, or increased diameter of the capillaries during the inflammatory response.
AIDS is caused by infection of T-cells by the ___ virus.
_______ cells (general term) ingest and destroy foreign invaders in the non-specific second line of defense.
_______ is released by basophils and mast cells found in the connective tissues during the inflammatory response.
A(n) _______ is a hypersensitivity of the immune system to an antigen in the environment.
Y-shaped proteins produced by the humoral immuntiy that recognize and bind specific antigens as well as destroy the pathogens bearing those antigens.
_______ (type of lymphocyte) are responsible for the antibody mediated (humoral) response.
The _____ mediated response is mounted primarily against cells of ones own body that are infected by intracellular invaders (e.g. viruses).
T-cells and B-cells are concentrated in the _____ tissues of the body, in places like the tonsils and spleen, amoung others.
Abundant white blood cells that are phagocytic but not derived from monocytes.
Class II _____ proteins bind antigens and form complexes on the surfaces of macrophages that are bound by helper T-cells.
Specific immunity is characterized by specificity and _________.
The bodies first line of defense against invasion consists of _______ barriers.
________ T-cells assist with antigen presentation in both the antibody and cell mediated responses.
The _______ response is part non-specific and is characterized by redness, swelling, heat, and pain.
_______ immunity is the bodies third line of defense.
The protein released by cytotoxic T-cells which attacks the cell membranes of infected cells.
_______ are substances release by immune cells which stimulate other immune cells.
_______ (type of lymphocyte) are primarily responsible for the cell mediated response but some of them are also very important in antigen presentation for the antibody mediated response.
When lymphocytes are activated, they make _____ cells.
