Memory cells are generated in adaptive immunity in response to a particular pathogen. A
feature of memory cells is what? - Answer ✅Upon re-exposure to that pathogen they can be
restimulated
The first step following the activation of a naïve T cell will result in what? - Answer ✅Expand in
numbers
Effector T and B cells that have been generated in an immune response are going to be used to
do what? - Answer ✅Eliminate the pathogen
After a pathogen has been eliminated by the immune response, most of the antigen specific
immune cells remaining will not be need and do what? - Answer ✅Die by apoptosis
The two major arms or approaches used by an adaptive immune response to eliminate
pathogen are called what? - Answer ✅Cell-mediated immunity and humoral immunity
What is the only infectious human disease to have been eradicated as a consequence of
vaccination? - Answer ✅Small pox
@2025 Exam Material 1
,Innate immunity is best defined as: - Answer ✅The system of immunity that can respond with
pathogens very quickly and relies on mechanisms that are inbuilt and respond in essentially the
same manner with the same exposure to pathogen
Any substance that is recognised by lymphocytes or antibodies is called a what? - Answer
✅Antigen
In adaptive immunity there are some key terms, features, or facts that are referred to again and
again so getting familiar with these and having a clear understanding of these will help your
learning. HUMORAL IMMUNITY: - Answer ✅Is associated with the production of antibodies by B
cells
In adaptive immunity there are some key terms, features, or facts that are referred to again and
again so getting familiar with these and having a clear understanding of these will help your
learning. PASSIVE IMMUNITY: - Answer ✅Is when antibodies or cells are transferred from
person to another
In adaptive immunity there are some key terms, features, or facts that are referred to again and
again so getting familiar with these and having a clear understanding of these will help your
learning. CELLULAR IMMUNITY: - Answer ✅Is often referring to the role of T cells in the immune
response
In adaptive immunity there are some key terms, features, or facts that are referred to again and
again so getting familiar with these and having a clear understanding of these will help your
learning. ACTIVE IMMUNITY: - Answer ✅Is when you get exposed to a pathogen and mount an
immune response
What is the specific term that defines the ability of the immune system to recognise a large
range of antigens? - Answer ✅Diversity
@2025 Exam Material 2
, The term that is used to define this feature of the adaptive immune response is called: - Answer
✅Specificity
So when you read or hear the term "naïve T lymphocyte" what does this tell you about the
lymphocyte? - Answer ✅It has all the features of a T cell but it has not yet been activated
(called into action)
The immune response that is generated upon the first exposure to an antigen is called the
secondary immune response. - Answer ✅The primary immune response
While we have a lot of T and B cells (estimate is about 10^12) circulating in our body, they don't
all respond to the same things or at the same time. In fact, the number of T or B cells that will
be specific for any one antigen (target from a pathogen for example) is low, which is why we
need so much diversity.So having said that, the estimated number if naive lymphocytes that can
react against any one antigen is: - Answer ✅About 1 in 100 000 cells
We now know that not too many cells have the potential to respond to an antigen, and they
would certainly not all be together in the same place at the same time. So when a lymphocyte
has been activated, it needs to make more of itself so the immune system can generate "an
army" with the right specificity to proceed to eliminate the pathogen. The term that is used to
describe this increase in cell numbers from a single cell to many cells is called: - Answer
✅Clonal expansion
For each of the words listed, pick the response that best describes the action of T cells. - Answer
✅Mediators of the cellular immune response
For each of the words listed, pick the response that best describes the action of B cells. - Answer
✅Mediators of the humoral (antibody) immune response
