(69 cards)
What is adaptive immunity?
A type of immunity that involves T cells and B cells responding to antigens.
What are adenoids?
Mass of lymphatic tissue in the nasopharynx.
What is an antibody?
Protein produced by B cells to destroy antigens.
What is an antigen?
Substance that the body recognizes as foreign; evokes an immune response.
What are axillary nodes?
Lymph nodes in the armpit (underarm).
What is a B cell (B lymphocyte)?
Lymphocyte that matures into a plasma cell to secrete antibodies.
What is cell-mediated immunity?
A type of adaptive immunity where T cells respond to antigens.
What are cervical nodes?
Lymph nodes in the neck region.
What is the complement system?
Set of proteins in the blood that help antibodies kill their target.
What are cytokines?
Proteins secreted by cytotoxic T cells to aid in antigen destruction.
What are interferons and interleukins?
Examples of proteins (cytokines) secreted to aid and regulate the immune response.
What is a cytotoxic T cell?
Lymphocyte that directly kills antigens; called CD8+ T cell.
What is a dendritic cell?
Antigen-presenting cell that shows T and B cells what to attack.
What is a helper T cell?
Lymphocyte that aids B cells and stimulates T cells; CD4+ T cell.
What is humoral immunity?
B cells produce antibodies after exposure to specific antigens.
What is immunity?
Body’s ability to resist foreign organisms and toxins.
What is the origin of the word immunity?
Comes from Latin immunis, meaning exempt or protected from.
What are immunoglobulins?
Antibodies such as IgA, IgE, IgG, IgM, and Ig; secreted by plasma cells.
What is immunotherapy?
Use of immune cells, antibodies, or vaccines to treat disease.
What are inguinal nodes?
Lymph nodes in the groin region.
What are interleukins?
Proteins (cytokines) that stimulate the growth of B and T lymphocytes.
What is interstitial fluid?
Fluid in the spaces between cells; becomes lymph when it enters lymph capillaries.
What is lymph?
Thin, watery fluid found within lymphatic vessels.
