NSG 5003 | NSG5003- Advanced Pathophysiology Exam 3 practice questions

The primary characteristic that differentiates the immune response from other protective mechanisms is that the immune response is: specific to the antigen that initiates it. B lymphocytes mature and undergo changes that commit them to becoming B cells in the: bone marrow. What is the term for the process in which lymphoid stem cells migrate from the bone marrow to the central lymphoid organs (the thymus or bone marrow) where they undergo cellular changes into either immunocompetent T cells or immunocompetent B cells? Generation of clonal diversity Which type of immunity is produced by an individual after either natural exposure to the antigen or after immunization against the antigen? Active acquired What type of immunity is produced when an immunoglobulin crosses the placenta? Passive acquired The portion of the antigen that is configured for recognition and binding is called an antigenic determinant or a(n): epitope The most important determinant of immunogenicity is the antigen's: foreignness Antibodies are produced in: plasma cells Which immunoglobulin is present in blood, saliva, breast milk, and respiratory secretions? IgA Which antibody indicates a typical primary immune response? IgM If a person had very low levels of Ig__, that individual is more susceptible to infections of mucous membranes. A Which are characteristics of the generation of clonal diversity? The process takes place in the primary (central) lymphoid organs (i.e., thymus and bone marrow). Which is an example of an endogenous antigen? Cancer cells Hypersensitivit
