Question 5

Which type of adaptive immunity will result from mother-to-baby IgA transfer via breast feeding?
A)naturally acquired active immunity
B)naturally acquired passive immunity
C)artificially acquired active immunity
D)artificially acquired passive immunity
E)None of these choices

Accepted Answer

The transfer of IgA antibodies from mother to baby via breast milk results in naturally acquired passive immunity, as the antibodies are passively transferred from the mother to the baby rather than actively produced by the baby's immune system.

Question 6

Which type of adaptive immunity will result from intravenous injection of immunoglobulins?
A)naturally acquired active immunity
B)naturally acquired passive immunity
C)artificially acquired active immunity
D)artificially acquired passive immunity
E)None of these choices

Accepted Answer

Intravenous injection of immunoglobulins is a form of artificially acquired passive immunity, where pre-formed antibodies from an external source are introduced into the body. This immunity is temporary and lasts only as long as the injected antibodies remain in the body.

B)B
C)C
D)D
E)E

Accepted Answer

Question 9

Natural passive immunity is associated with which of the following?
A)Vaccination
B)Exposure to a microbe resulting in antibody formation
C)Receiving booster shots
D)Transfer of IgG from mother to fetus
E)Intravenous injection of antibodies

Accepted Answer

Natural passive immunity refers to the transfer of antibodies from a mother to her fetus during pregnancy or from a mother to her infant through breast milk. This type of immunity is considered "natural" because it occurs without the deliberate intervention of healthcare professionals. The most common type of antibody transferred in this manner is IgG, which can provide protection against a variety of infections.

Question 10

Lymph flowing from the afferent lymphatic vessel will travel next to which structure in the figure? 
A)A
B)B
C)C
D)D
E)E

Accepted Answer

The lymph flows from the afferent lymphatic vessel to the lymph node (represented by the oval structure in the figure) and passes through the subcapsular sinus (which surrounds the lymph node) before entering the cortical sinuses. The B region in the figure represents the subcapsular sinus, which is the first location where the lymph will travel after entering the lymph node. Therefore, choice B is the correct answer.

Which structure in the figure is a palatine tonsil? 
A)C
B)J
C)G
D)F
E)D

Question 13

Which cells increase the permeability of blood vessels by releasing histamine?
A)neutrophils
B)eosinophils
C)lymphocytes
D)mast cells
E)macrophages

Accepted Answer

Mast cells are the cells that release histamine, which can increase the permeability of blood vessels. Neutrophils, eosinophils, lymphocytes, and macrophages do not release histamine.

Question 14

Which cytokine released by macrophages acts on the hypothalamus to raise the body temperature during fever?
A)Interleukin-1
B)Interleukin-2
C)Interleukin-4
D)Gamma interferon
E)Perforin

Accepted Answer

Interleukin-1 is released by macrophages during infection and acts on the hypothalamus to raise the body temperature, resulting in fever.

Question 15

Which immunoglobulin is a pentamer?
A)IgG
B)IgM
C)IgD
D)IgA

Accepted Answer

IgM is the only immunoglobulin that exists as a pentamer, meaning it is made up of five identical monomers linked together by disulfide bonds. This structure allows for increased binding avidity and efficient neutralization of antigens.

Question 16

What type of cell is not located in area A in the figure? 
A)B cells
B)dendritic cells
C)macrophages
D)T cells
E)None of these types of cells

Accepted Answer

The answer of What type of cell is not located...

Question 17

Plasma cells are located in which area in the figure? 
A)A
B)B
C)C
D)D
E)None of these choices

Accepted Answer

Plasma cells are a type of B cell that secretes antibodies, so they are located in the lymph node's medulla (D), which contains many plasma cells.
