PSL 310- Exam 2 Questions with All
Correct Answers 2026.
Proteins in plasma - Answer albumin, fibrinogen, globulin
globulin - Answer important for transport. Antibodies are these.
fibrinogen - Answer blood clotting
hematocrit - Answer percentage of the total blood volume taken up or occupied by red blood
cells packed down by centrifuging
polycythemia - Answer elevated hematocrit that occurs in high altitude.
ethrythropoiesis - Answer red blood cell (erythrocyte) production.
hemoglobin - Answer 4 polypeptides with four iron containing heme groups. O2 binds to the
iron.
oxyhemoglobin - Answer hemoglobin with oxygen
deoxyhemoglobin - Answer hemoglobin without O2
bilirubin - Answer a bile pigment leftover from broken down hemoglobin. (the heme). Some
goes in bile, some in urine, and gives the color of plasma
erythropoietin - Answer hormone from the kidney and liver that stimulates production of red
blood cells
aplastic anemia - Answer caused by the failure of bone marrow to make rbcs
hemolytic anemia - Answer excessive rupture of rbcs. ex: sickle cell anemia
basophil - Answer histamine granuales.
, histamine - Answer increases permeability to protein, increases blood flow by vasodilation,
increases fluid in ISF (edema)
eosinophil - Answer releases chemicals that kill parasites. Multicellular organism like a worm.
Attaches to it and kills it with toxic molecules
neutrophils - Answer phagocyte. Important in infections with bacteria and in inflammation.
granulocytes - Answer -produced in red bone marrow
-the "phils"
-go to tissues to do their work. Live for a few days there.
monocytes - Answer -released from red bone marrow
-circulate for a while
-go to tissues and become large macrophages
-can live for months or years, depending on amount of phagocytosis
lymphocytes - Answer protect against specific invaders by reacting to specific antigens.
antigen - Answer part of the invader or a toxin. Usually a protein. A foreign molecule that
causes the specific immune response against it.
inflammation - Answer Bacteria enter the body at an injury site. Chemicals are released from
the cells in the area, including histamine.
interferon - Answer protein released by cells infected with a virus, and protects other cells
from infection by other viruses. Is nonspecific.
B cells/lymphocytes - Answer become plasma cells. Secrete antibodies into blood. These
antibodies mark the invader and neutralize toxins
helper t cell - Answer secretes chemicals that activate other immune cells.
cytotoxic t cell - Answer attacks a specific invader with a specific antigen. Releases chemicals
to kill the cell. Virus infected cells and cancer cells
