BMS 251-LAB- BLOOD TYPING AND
GENETICS EXAM QUESTIONS AND
ANSWERS GRADED A+ 2025/2026
Erythrocyte - ANS This is an ___________. Its function is to transport oxygen through the
body.
basophil - ANS This is a ________. The nucleus is typically bilobed, though it may be hard to
see because of the purple-ish cytoplasmic granules. Its function is to initiate immune response
and release histamine and heparin.
eosinophil - ANS This is an __________. The nucleus usually has two lobes connected by a
thin strand. They have large red cytoplasmic granules. They function in phagocytosis of antigen-
antibody complexes, allergens, and inflammatory chemicals, and release enzymes to destroy
parasitic worms.
platelet, hemostasis - ANS This is a ________, or thrombocyte. These are pieces of degraded
cells that function in __________ (clotting to stop bleeding).
monocyte - ANS This is a ________. They have large vaguely u-shaped nuclei. They are the
largest leukocytes, and function in phagocytosis.
neutrophil - ANS This is a __________. They have multi-lobed nuclei (usually 3-5 lobes) that
are connected by thin strands. They have very fine cytoplasmic granules that may appear pink.

, They function in the phagocytosis of infectious pathogen, especially bacteria, and in the release
of antimicrobial agents.
lymphocyte - ANS This is a __________. They have very large, mostly round nuclei. There are
three types, and they function in humoral immune response, cell-mediated immune response,
and the killing of infected or cancerous cells.
thrombocytes, megakaryocytes - ANS ____________ (platelets) are bits of cell that come
from the degradation of ______________.
agranulocytes - ANS _____________ are the class of leukocytes that have no cytoplasmic
granules.
granulocytes - ANS ____________ are the class of leukocytes that have cytoplasmic granules,
giving them a speckled appearance.
monocytes, lymphocytes - ANS The two agranulocytes are _________ and ___________.
neutrophils, eosinophils, basophils - ANS The three granulocytes are ___________,
__________, and _________.
Formed elements- 1. Erythrocytes 2. Leukocytes 3. Platelets - ANS Describe the components
and physical properties? of whole blood
-Biconcave discs-allow RBCs to fit single file through capillaries
-No organelles
-Function- transport oxygen and carbon dioxide around body via hemoglobin
--Hemoglobin- protein molecule that carries oxygen and CO2. Each has 4 globin chains with
heme group. Heme has Fe2+ in center and O2 binds to Fe2+ - ANS Describe the structure
(including hemoglobin) and function of Erythrocytes
