Thymus gland
- B.
Regional lymph nodes
- C.
Bone marrow
- D.
Spleen
- 13.What is the term for the process in which lymphoid stem cells migrate from the bone marrow to the central lymphoid organs (thymus or bone marrow) where they undergo cellular changes into either immunocompetent T cells or immunocompetent B cells?

- A.
Passive acquired
- B.
Active acquired
- C.
Passive innate
- D.
Active innate
- 15.Which type of immunity is produced when an immunoglobulin crosses the placenta?
- A.
Passive acquired

- 16.The portion of the antigen that is configured for recognition and binding is called an antigenic determinant or a(n):
- A.
Immunotope
- B.
Paratope
- C.
Epitope
- D.
Antigenitope
- 17.The most important determinant of immunogenicity is the antigen's:
- A.
Size
- B.
Foreignness
- C.
Complexity
- D.
Quantity
- 18.When antigens are administered to individuals to produce immunity, why are different routes of administration used (IV, SQ, nasal)?
- A.
Different routes allow the speed of onset of the antigen to be varied, with the IV route being fastest
- B.
Some individuals appear to be unable to respond to an antigen by a specific route, thus requiring the availability of different routes for the same antigen
- C.
Antigen-presenting cells (APCs) are highly specialized and thus require stimulation by different routes
- D.
Each route stimulates a different lymphocyte-containing tissue resulting in different types of cellular and humoral immunity
- 19.How are functions of the major histocompatibility molecules and CD1 molecules alike?
- A.
They are both antigen-presenting (APC) molecules
- B.
They both bind antigens to antibodies
- C.
They both secrete interleukins during the immune process

Helper T lymphocytes
- B.
The thymus gland
- C.
Plasma cells
- D.
The bone marrow
