Example Questions

Example Question #33 : Immune Physiology

Which of the following is a key difference between the innate and the adaptive immune systems?

Possible Answers:

The adaptive immune system fights antigens at a more efficient rate during subsequent exposures after the first

The adaptive immune system fights bacteria, while the innate immune system fights viruses

The innate immune system cannot attack antigens that it does not recognize

The innate immune system can fight cancers and autoimmune reactions, while the adaptive immune system can only fight bacteria

The adaptive immune system utilizes T-cells, whereas the innate immune system utilizes B-cells

Correct answer:

The adaptive immune system fights antigens at a more efficient rate during subsequent exposures after the first

Explanation:

The two types of immune reactions found in the human body are the innate and adaptive immune systems. The innate immune system is the first defense for common antigens that enter the body, and will respond to any and all foreign antigens that it detects. The adaptive immune system utilizes antibodies to fight antigens that reappear in the body during subsequent exposures, and allows the system to more uniquely attack the specific antigen. Both systems can respond to a variety of different pathogens, including bacteria and viruses.

Example Question #34 : Immune Physiology

Which of the following organs is not involved in the immune response?

Possible Answers:

Thymus

Spleen

Lymph nodes

Heart

Bone marrow

Correct answer:

Heart

Explanation:

The heart is the only organ listed that is not involved in the immune response. The thymus is the site of T-cell maturation, while bone marrow is the site of B-cell maturation. The lymph nodes and spleen are sites of blood filtration to ensure that there are no pathogens in the system.

Example Question #35 : Immune Physiology

Which of the following is not a characteristic of the adaptive immune system? 

Possible Answers:

Differentiates between foreign and self cells 

Takes a week or two to develop 

Produces antibodies 

General response to an invasion 

Memory component 

Correct answer:

General response to an invasion 

Explanation:

The innate immune system is the general, non-specific response to pathogens. It does not involve a memory component. The adaptive immune system is the more complex, specific response to pathogens. The adaptive immune system takes longer to develop, is able to discriminate between self cells and non self cells, and has a memory component so the second reaction is a quicker response to infection. 

Example Question #4 : Help With Other Adaptive Immunity Physiology

Where does the processing and maturation of T-lymphocytes occur? 

Possible Answers:

Spleen

Thyroid 

Blood 

Thymus 

Bone marrow 

Correct answer:

Thymus 

Explanation:

The thymus is one of two primary lymphoid tissues and is the site of T cell processing, and maturation. These cells are sometimes referred to as thymocytes. The bone marrow is the other primary lymphoid tissue and is the site of B cell maturation. 

Example Question #36 : Immune Physiology

Which is an organ of the immune system?

Possible Answers:

Heart

Spleen

Gallbladder

Liver

Stomach

Correct answer:

Spleen

Explanation:

Tissues of the immune system are classified as central (primary) or peripheral (secondary). Peripheral tissues initiate adaptive immune responses. Peripheral lymphoid organs include: lymph nodes, spleen, and the mucosal and cutaneous immune systems (ex: peyers patches in the gastrointestinal tract).
