Chapter 14 - Vocabs Flashcards
Adaptive Immunity
Ability to recognize and remember specific antigens and mount attack on them. Humoral (B cells) and cell-mediated immunity (T cells are examples)
Adenoids
Mass of lymphatic tissue in the nasopharynx
Antibody
Protein produced by B cells to destroy antigens
Antigen
Substance that the body recognizes as foreign; evokes an immune response
Auxiliary nodes
Lymph nodes in the armpit (underarm)
B Cell (B lymphocyte)
Lymphocytes that matures into a plasma cell to secrete antibodies
Cell-mediated immunity
T cells (cytotoxic, helper and suppressor) respond to antigens and destroy them; a type of adaptive immunity
Cervical Nodes
Lymph nodes in the neck region
Complement system
Proteins in the blood that helps antibodies and kill their target
Cytokines
Proteins secreted by cytotoxic T cells to aid in antigen destruction. Examples are interferon and interleukins
Cytotoxic T cells (CD8+ T cell)
Lymphocytes that directly kills antigens
Dendritic cell
Antigen-presenting cell; shows T and B cells what to attack
Helper T cell (CD4+ T cell)
Lymphocytes that aids B cells and stimulates T cells
Humoral Immunity
B cells produce antibodies after exposure to specific antigens; a type of adaptive immunity
Immunity
Body’s ability to resist foreign organisms and toxins that damage tissues and organs. Includes both natural and adaptive
