A&P2 BIO 142 EXAM 1 LATEST 2024-2025. ALREADYGRADED A+
1. a straw-colored clear solution that makes up about 55% of whole blood. It mostly
consists of water, but also contains a variety of dissolved and suspended chemical
substances, from small blood gas molecules like carbon dioxide and oxygen to
larger molecules like complex proteins.
is the liquid component of blood, which accumulates at the top of a glass tube after
centrifugation.: Plasma
2. make up about 45% of whole blood. Composed of Erythrocytes or red blood
cells, Leukocytes or white blood cells, and Platelets or thrombocytes.: Formed
elements
3. are anucleate, biconcave discs containing hemoglobin, which reversibly binds
oxygen, CO2 and H+, and therefore has the function of transporting of blood
gases.: Erythrocytes or red blood cells
4. are nuclei-containing cells of the immune system. Five different white blood cells
can be identified when blood is viewed microscopically.: Leukocytes or white blood
cells
5. are cellular fragments involved in blood platelet plug formation and hemostasis
(blood clotting).: Platelets or thrombocytes
6. a motorized device used to spin a horizontally positioned glass tube of blood at a
high speed for 5 minutes. The centrifugal force produced by the spinning device
causes the heavier formed elements of the blood to accumulate at the bottom of
the glass tube and the lighter plasma to remain at the top.: centrifuge
7. the percentage of a whole blood sample accounted for by erythrocytes or
RBC's.: Hematocrit or the packed cell volume (PCV)
8. (height of packed RBC's/ height of blood sample) x 100.: The equation used to
determine hematocrit is:
9. 36-46%.: The normal hematocrit range for adult females (living at sea level) is
10. 42-52%.: The normal hematocrit range for adult males (living at sea level) is
11. a mostly clear narrow region between the PCV and the plasma consisting of
white blood cells and platelets.: buffy coat
12. a clinical sign indicating that the number of circulating RBC's and/or the
amount of circulating hemoglobin is below normal. Anemia results in an inability to
transport an adequate amount of oxygen to tissues.: Anemia 13. a serious disorder
that results when the bone marrow no longer producing RBC's, so the number of
RBC's and the amount of hemoglobin both decrease.: Aplastic anemia
, .
14 a reduced number of RBC's and reduced amount of hemoglobin due to bleeding.:
Hemorrhagic anemia
15. a reduction in the number and size of RBC's and decreased hemoglobin due to
a lack of iron.: Iron deficiency anemia
16. a disorder in which there is a reduced number of RBC's in the circulation due
to a lack of vitamin B12. The deficiency of B12 causes decreased DNA synthesis
resulting in RBC's that are abnormally large. Because this anemia results in the
production of large cells, it is classified as a megaloblastic anemia.: Pernicious
anemia
17. a general term that refers to an elevated amount of RBC's relative to the entire
sample of blood (increased hematocrit).: Polycythemia
18. reduces the amount of plasma relative to the number of RBC's.: Dehydration
19. increases the production of the hormone erythropoietin, which stimulates
RBC production.: Living at high altitude
20. a disease of the bone marrow that results in an increased number of RBC's in
circulation due to overproduction of cells by the bone marrow.: Polycythemia
vera

marathon. Which of the following scenarios best correlates with this patient? a.
polycythemia vera
b. hemorrhage
c. dehydration
d. pernicious anemia
[Ex 2, hematocrit determination]
30. : 4. Sample 4 is from 46-year-old female who lives in Virginia Beach. Which of the
following scenarios best correlates with this patient? a. polycythemia vera
b. hemorrhage.
c. normal

31. : 5. Sample 5 is from a 75-year-old female who lives in Miami Beach. Which of the
following scenarios best correlates with this patient? a. normal
