Question 1

Which of the following is NOT an attribute of adaptive immunity?

Accepted Answer

Immediate response

Question 2

B lymphocytes (B cells) mature in which of the following locations?

Accepted Answer

Bone marrow

Question 3

Which of the following best describes the function of the lymphatic system in adaptive immunity?

Accepted Answer

It screens tissues for foreign molecules and pathogens.

Question 4

Which of the following is a primary lymphoid organ?

Accepted Answer

Thymus

Question 5

What is the main difference between cell-mediated and antibody (humoral) immune responses?

Accepted Answer

Cell-mediated responses involve T cells, while humoral responses involve B cells.

Question 6

Which of the following statements about lymph is correct?

Accepted Answer

Lymph is a liquid that arises from fluid leaked from blood vessels into surrounding tissue.

Question 7

A patient has a genetic defect that prevents the maturation of T lymphocytes. Which organ is most likely affected?

Accepted Answer

Thymus

Question 8

Which of the following is a secondary lymphoid organ?

Accepted Answer

Lymph nodes

Question 9

The property of adaptive immunity that allows it to respond more rapidly and effectively upon subsequent exposures to a pathogen is called:

Accepted Answer

Immunological memory

Question 10

Which of the following best explains why the lymphatic system is considered a 'one-way' system?

Accepted Answer

Lymphatic vessels conduct lymph from tissues and return it to the circulatory system, not the other way around.

Question 11

A researcher is studying the immune response in the tonsils. Which type of lymphoid organ is she investigating?

Accepted Answer

Secondary lymphoid organ

Question 12

Which of the following is NOT a function of adaptive immunity?

Accepted Answer

Producing a rapid, non-specific response to all pathogens

Question 13

A patient with a damaged spleen is at increased risk for infections because the spleen:

Accepted Answer

Filters blood and helps initiate immune responses to blood-borne pathogens

Question 14

Which of the following best describes the concept of 'clonality' in adaptive immunity?

Accepted Answer

Each lymphocyte produces a unique receptor and can multiply to form a population of identical cells when activated.

Question 15

Which of the following scenarios best illustrates the principle of 'unresponsiveness to self' in adaptive immunity?

Accepted Answer

A T cell ignores the body's own healthy cells and does not attack them.

Question 16

A patient is exposed to a pathogen for the first time. Which attribute of adaptive immunity ensures that the body will respond more efficiently if exposed to the same pathogen again?

Accepted Answer

Immunological memory

Question 17

Which of the following best describes the composition of lymph?

Accepted Answer

Lymph is a liquid with a composition similar to blood plasma, arising from fluid leaked from blood vessels into surrounding tissue.

Question 18

Which of the following equations best represents the relationship between the number of lymphocytes ($$N) $$after $$n$$ rounds of clonal expansion, if each lymphocyte divides into two daughter cells per round?

Accepted Answer

$$N = 2^n$$

Question 19

A patient with a deficiency in mucosa-associated lymphoid tissue (MALT) would most likely have increased susceptibility to infections in which area?

Accepted Answer

Mucosal surfaces such as the gut and respiratory tract

Question 20

Which of the following best explains why adaptive immunity is considered 'specific'?

Accepted Answer

It recognizes and responds to particular antigens unique to each pathogen.
