PATHOPHYSIOLOGY EXAM 2 SPRING 2023
QUESTIONS AND CORRECT DETAILED
ANSWERS 2025-2026 (VERIFIED ANSWERS)
||ALREADY GRADED A+||NEWEST VERSION
\What are the two flavors of lymphocytes and what do they do? ANS: T and B. T cells
kill things, and B cells morph into plasma cells which create antibodies.
What are antigens and what do they do? ANS: Antigens are foreign bodies that induce
an immune response.
What is an HLA or MHC? ANS: Molecules on the surface of all cells that let our
immune system know it is "self".
Two mechanisms of the lymphoid immune system ANS: Cell-mediated immunity (T
cells) and antibody mediated immunity (B cells).
Three main types of lymphoid cells ANS: T cells, B cells, Natural Killer (dendritic) cells
Name the primary and secondary lymph organs ANS: Primary: bone marrow, thymus
(hence T cells)
Secondary: spleen, lymph nodes, peyer's patches

What do T cells do? ANS: CD4 cells release cytokines which tell B cells to eat stuff,
CD8 cells attack cancer cells.
T/F Natural killer cells need to see an antigen before they can kill it. ANS: False, they
"naturally" know how to fight things. This is why they make up part of the innate immune
system.
What do B cells do? ANS: Turn into plasma cells which produce antibodies, or turn
into memory cells which remember antigen information. They also serve as antigen
presenting cells.
Where do antibodies come from? ANS: Plasma cells (not B cells)
What are immunoglobulins and what do they do? ANS: Globular, Y shaped antibodies
that are produced by plasma cells.
What percent of blood proteins are immunoglobulins? ANS: 20%
