A&P II- Exam 3: Connect (Lymphatic andImmunity) 2024 with questions and answers
Which cell phagocytizes an antigen and displays fragments of it on its surface?
Antigen-Presenting Cell (APC)
Which body system maintains fluid balance, absorbs lipids, and protects the body
against pathogens?
Lymphatic System
Which primary lymphoid organ is the site of B cell maturation?
Red Bone Marrow
Which of the following statements accurately describes the difference between cellular
and humoral immunity?
Cellular immunity directly attacks pathogens and infected cells while humoral immunity
releases antibodies to do so.
Indicate whether the label identifies an adaptive or innate immunity.
The structures and cells of the immune system can be characterized as participating in
either adaptive or innate immunity. The structures that provide resistance to a broad
grouping of pathogens without producing or requiring any memory are called innate.
Drag each label into the appropriate position to identify what type of immunity is
classified by each label.
Immunity can be acquired through natural or artificial processes. Natural processes
require either mother-to-offspring transference or through illness whereas artificial
processes usually require modern medical interventions in the form of inoculation or
injections. Passive immunity involves only antibodies that are received from an outside
source whereas active immunity refers to the production and subsequent memory
formation of immune response.
Match each leukocyte listed with its correct defensive function.
Leukocytes play an important role in both nonspecific defenses and specific immunity.
They are integral in both the second and third lines of defense. Each leukocyte has
specific functions to aid the immune system.
Drag each cell into the appropriate position to identify whether it is associated with
antibody-mediated immunity, cell-mediated immunity, or both.
, Cell-mediated immunity is useful in combating pathogenic elements inside of self-cells
whereas antibody-mediated immunity works to defend against pathogens that exist and
are created externally to one's cells. Cell-mediated responses utilize the activation of
Cytotoxic T-cells, which are charged with destroying the infected cells. Antibody-
mediated responses utilize B-lymphocytes to produce extraordinary quantities of
antibodies, which work to render pathogens harmless via four mechanisms:
neutralization, precipitation, agglutination, and complement fixation.
Read each description regarding cellular and humoral immunity. Then, click and drag
each into the appropriate category based on the form of immunity to which it applies.
Cellular immunity is a form of specific defense in which T lymphocytes directly attack
and destroy diseased or foreign cells, and the immune system remembers the antigens
of those invaders to prevent them from causing disease in the future. Humoral immunity
is a more indirect method of defense than cellular immunity. Instead of directly attacking
invaders, B lymphocytes produce antibodies that bind to antigens and tag them for
destruction.
A small organ found along the course of a lymphatic vessel that filters the lymph and
functions as an activation site for B and T cells is called a lymph __________.

We have an expert-written solution to this problem!
Drag each characteristic on the left into the appropriate position on the right to identify
whether it is associated with T cells, B cells, or both.
Lymphocytes are vital in both forms of specific immunity. T cells are the most numerous
and include the helper, regulator, and cytotoxic cell lines. B cells can differentiate into
plasma cells responsible for the mass production of antibodies when stimulated. Both
form memory cells and thus convey long-term immunity following a primary exposure.
Complete each sentence explaining antibody function by dragging the proper label into
the appropriate position.
Classify the following images into the type of defense it represents.
