a.
Summary Introduction
To explain: The way in which great diversity of B and T cells is produced.
Introduction: The immune system is classified into two types, namely innate immune system and adaptive immune system. The adaptive immune system is either active or passive. The two types of adaptive immunity are cell-mediated and humoral immunity. The cells that are involved in the adaptive immune system are T and B lymphocytes. The adaptive immune system provides the ability to recognize an antigen and create immunologic memory.
b.
Summary Introduction
To explain: Prevention of B cells and T cells from reacting against their own body molecules.
c.
Summary Introduction
To explain: Clonal selection.
d.
Summary Introduction
To explain: Immunological memory.

What occurs in an antibody-mediated response? Select all that apply.
Cytokines induce the activated cytotoxic T cell to divide repeatedly and become many effector cells and memory cells bearing the same antigen as the original cytotoxic T cell.
Cytokines induce the B cell to undergo repeated mitosis and differentiate into many effector B cells and memory B cells.
Effector B cells begin making and secreting huge numbers of antibodies that recognize the same antigen as the original B cell.
Effector helper T cell receptors bind to corresponding antigens on a B cell and produce cytokines.
What is innate immunity? List the four types of barriers which protect the body from the entry of the foreign agents.
Name three types of T cells.

- What occurs in a cell-mediated immune response? Select all that apply. Naive B cells bind to antigen on the surface of a bacterium and become activated. A dendritic cell incorporates digested viral antigen-MHC complexes. Naive cytotoxic T cells bind to antigen on antigen-presenting dendritic cells and become activated. Effector cytotoxic T cells circulate through the body and kill any body cells that display the viral antigen-MHC complexes.arrow_forwardWhich is/are involved in reacting to virus-infected cells?

Multiple Choice Two populations of cells are formed: memory T cells and effector TH cells, the effector TH cells play a role in activating B cells. Two populations of cells are formed: effector TH cells and effector TC cells; these work together to activate B cells and macrophages. Activated TH cells produce cytokines that stimulate dendritic cells, converting them into antigen-presenting cells. Two populations of cells are formed: helper T cells and cytotoxic T cells; the TH cells activate B cells and the TC cells target virus-infected cells.
