BIO 202: Blood Review Guide Questions With Complete
Solutions
1. List AND define some common Latin prefixes and suffixes
associated with the circulatory system. Correct Answers -
Hemo/a-: blood
- Anti-: against
- Erythros-: red
- Leukos-: white
- cyte: cell
- penia: poverty, not enough
- osis: too many
- Thrombos-: clot
- stasis: halt, stop
10. Explain the importance of a RBC's biconcave disc shape.
Correct Answers - The 'dent' in each side of a red blood cell,
like its small size, increases the amount of surface area in
relation to the volume of the cell, giving it a large surface area to
volume ratio. This large surface area means that oxygen can
diffuse quickly into or out of the cell
1. High surface-to-volume ratio:
- quickly absorbs and releases oxygen
2. Discs form stacks: -Rouleau
- smoothes flow through narrow blood vessels
3. Discs bend and flex entering small capillaries:
- 7.8 µm RBC passes through 4 µm capillary
*folded pizza to get into mouth - MMMMM PIZZA!
, 11. Describe the structure AND function of hemoglobin. Spend
some time on this one! Correct Answers Hemoglobin (Hb)
molecule responsible for transporting O2 & CO2 to & away
from tissues
Single pigment molecule of heme
i. Iron (Fe) ion that interacts with O2 molecule =
oxyhemoglobin
1. Bright red
ii. Fe not bound to O2 = deoxyhemoglobin
1. Dark red/burgundy
4 oxygen molecules can bind to one 1 molecule of Hb
12. Explain how hemoglobin's affinity for oxygen changes as
oxygen is unloaded into peripheral tissues. Correct Answers
13. Explain why breathing high levels of carbon monoxide (CO)
can lead to death. Correct Answers
14. Diagram AND label the process of erythrocyte homeostasis,
making sure to focus on the importance of erythropoietin.
Correct Answers Due to low Oxygen levels in the
blood(hypoxemia)
-drop in RBC count causes kidneys to stimulate hormone
Erthyropoietin(EPO).
-EPO will stimulate red bone marrow
-RBC count will increase in about 3-4 days
15. Diagram AND label the process of RBC recycling making
sure to include:
