WSU BIO 315 LECTURE EXAM 3 QUESTIONS AND
ANSWERS
Function of blood - Correct Answers -carry respiratory gases, nutrients, wastes and
hormones and helps regulate body temp
Volume of blood: males - Correct Answers -5-6 liters
Volume of blood: females - Correct Answers -4-5 liters
composition blood - Correct Answers -contains cellular and liquid components with
blood cells and plasma
hematocrit - Correct Answers -% of red blood cells
males 47% ish
females 42% ish
how is red blood cells counted - Correct Answers -flow cytometry (laser) or impedance
(electrical resistance)
blood plasma - Correct Answers -straw colored and sticky fluid made if 90% water,
about 55% of whole blood containing ions, nutrients, wastes, and proteins
3 main blood proteins - Correct Answers -albumin, globulins, fibrinogen
abumin - Correct Answers -most abundant, maintains osmotic pressure
globulins - Correct Answers -alpha and beta, transport metal ions, lipids and lipid
hormones
gamma are antibodies (immunoglobulins)
separating blood components - Correct Answers -draw blood, put in centrifuge, comes
out plasma layer (55%), buffy coat with are leukocytes and platelets (<1%) and
erythrocytes (45%)
buffy coat and platelets are the formed elements
erythrocytes - Correct Answers -red blood cells transporting oxygen, majority of formed
elements
myeloid stem cell - Correct Answers -give rise to all other blood cells
, erythrocytes are formed from - Correct Answers -proerythroblasts
megakaryocytes (platelets) are formed from - Correct Answers -megakaryoblasts
granulocytes (eosinophil, basophil, neutrophil) are formed from - Correct Answers -
myeloblasts
leukocytes - Correct Answers -white blood cells protecting body from infections outside
blood stream in loose connective tissue
diapedesis - Correct Answers -circulates leukocytes leaving capillaries by squeezing
between endothelial cells
two types - Correct Answers -granulocytes (enzyme filled vesicles) & agranulocytes
(lack vesicles)
per rhexis - Correct Answers -loss of formed elements through ruptured vessels
platelets - Correct Answers -not whole cells (fragments) that break off megakaryocytes
in bone marrow initiation blood clots with platelet plug preventing blood loss from injured
blood vessels
acidic dye - Correct Answers -eosin, pink
basic dye - Correct Answers -hematoxylin or methylene blue, blue or purple
hemaglobin - Correct Answers -oxygen carrying protein
binocava shape of erythrocytes - Correct Answers -30% more surface area originating
in bone marrow living 100-120 days
neutrophils (granulocytes) - Correct Answers -most abundant leukocyte that
phagocytizes bacteria and releases enzymes that contains enzymes to destroy bacteria
multi-lobed (2-6)
eosinophils (granulocytes) - Correct Answers -1-4% of white blood cells, stained by
eosin (pink) turning off allergic reactions and help fight off parasitic infections
basophils (granulocytes) - Correct Answers -least numerous leukocytes normally has
two lobes staining basic dyes (purple) secreting histamine which functions in
inflammation mediation
lymphocytes (agranulocytes) - Correct Answers -20-40% of white blood cells, most
important staining dark purple and effective in fighting infectious organisms
