Correct!
IgG
Chapter 16

are also known as natural killer lymphocytes
Correct!
are involved in killing cancer cells
are the target cells of HIV
All of the above
None of the above
Chapter 16, T Lymphocytes (T Cells) section
Question 11
10 / 10 pts
(TCO 9) List and describe the structure of each of the five classes of antibody molecules. Which one is produced first in the disease process? Which is the most prevalent?
Answer:
IgM comes first and then convert
I gG is the most come and long lasting
IgE release histamen
IgD remains attached to b cells
IgA body secrections
Chapter 16, B Lymphocytes (B cells) and Antibodies section
IgM is a pentamer of five subunits. IgG is a monomer, the most common and longest lasting. IgA is associated with secretions; secretory IgA is a dimer. Monomeric IgA is also found circulating in the bloodstream. IgE is a monomer and associated with allergic reactions and helminth infections. IgD is a monomer and often membrane bound. Its function is not known. IgM is produced first during the infection response. IgG is the most prevalent antibody.

the remains of a phagosome after digestion
3) The fluid called pus _____.
contains WBCs and dead tissue
4) Membrane attack complexes (MAC) _____.
are holes in the cell membranes of pathogens
5) A wandering macrophage may leave the bloodstream.
True
6)A human’s cellular ability to recognize and then defend against microbial invaders and their products is called _____.
adaptive immunity
7) The humoral immune response is attributed to the action of _____.
B lymphocytes
8) The most prevalent type of antibody in the blood is _____.
IgG
9) Which of the following are functions of IgG?
All of the above
10) Memory B cells _____.
do not secrete antibodies
Question 11:
A pregnant woman is sick with a rash, and her doctor is not sure whether she has fifth disease (caused by parvovirus B19) or rubella (caused by rubella virus). The physician requests antibody titer tests. The results are that antiparvovirus B19 antibodies are primarily IgM, and antirubella virus antibodies are all IgA and IgG.
(a) Which disease does the pregnant woman currently have? How do you know?
(b) Which disease has she had in the past? How do you know?
Answer:
(a) The pregnant woman currently has fifth disease. IgM is produced during the initial stages of an infection, so its presence indicates that the woman has a recent infection with fifth disease.
(b) The pregnant woman has had rubella in the past, or been vaccinated against it. She has antibodies to the virus but no IgM indicating a recent infection. [Show Less]
