Exam 37: Immunity

There are five antibody classes: __________, __________, __________, __________, and __________.(Ig stands for __________.)

Some clones of the original immune cells are __________ cells, long-lived B and T cells reserved for future encounters with the antigen.

MATCHING Matching.Match each term with the most appropriate statement. a.cells that do not divide, die in less than a week, and secrete antibodies b.cells that directly destroy body cells already infected by viral or fungal parasites, as well as mutant and cancerous cells c.lymphocytes that are held in reserve, circulate in the bloodstream, and enable a rapid response to subsequent encounters with the same invader d.able to lyse cells by forming pore complexes e.cells that are produced in the bone marrow, are never changed by the thymus, and manufacture antibodies f.able to destroy cells but not dependent on recognition of antigen-MHC complexes g.a class of proteins that help cells of the immune system communicate h."big eaters" that alert other lymphocytes to the invasion of specific antigens i.immature cells that may or may not be committed to develop into one of several mature cell types j. a group of cells that are all produced asexually from one original parent cell k.surface patterns of nonself molecules or particles l. proteins released by cytotoxic T cells to destroy target cell membranes m. preparation injected into the body to elicit a primary immune response n. one of this group has been identified as the causative agent of AIDS -macrophages

The cell-mediated response involves all of the following EXCEPT

All of the following are autoimmune diseases EXCEPT

Classification.Respond to the following statements in reference to the five items listed below. a.antigens b.antibodies c.helper T cells d.cytotoxic T cells e.effector B cells -These produce immunoglobulins in response to the reinvasion by a virus.

What are responsible for the rapid mobilization of the immune response after a subsequent attack by a pathogen?

Use the figure above to answer the following questions. -The letter "B" from the above figure represents

In AIDS, the body's reduced capacity for adaptive immunity is due directly to the destruction of ____ cells.
