Blood Quest Review
1. What are 3 important blood components discussed in class? What are their functions?
Red blood cells- carry oxygen, white blood cells- defend the body, platelets- blood clotting
2. Why is it impossible for red blood cells to divide, grow, or synthesize proteins?
They lack a nucleus
3. Where are all blood cells formed?
red bone marrow
4. What is the hormone that controls red blood cell formation? What does it respond to?
erythropoietin, it responds to decreased oxygen levels in the blood
5. What is the blood clotting process called? How many phases are there?
Hemostasis, 3 phases
6. What is the name for blood cell formation?
hematopoiesis
7. What disease is related to a red blood cell’s decreased ability to carry oxygen?
Anemia
8. Leukopenia is a decrease in the number of what?
White blood cells
9. What is thrombocytopenia?
A condition that occurs when your blood has a platelet deficiency
10. What molecule does oxygen bind to? How many oxygens can bind to one of these?
hemoglobin; one molecule of hemoglobin can bind to 4 oxygens
11. What is the name of the molecule that is on red blood cells that determines your blood type?
Antigen

Fill in the blanks with the correct words, and then determine which phase of hemostasis it is
describing.
1. Injured tissue releases thromboplastin. PF3 interacts with thromboplastin, blood protein
clotting factors, and calcium ions to trigger a clotting cascade. Prothrombin is converted
to
thrombin. This enzyme joins fibrinogen into hair-like fibrin, creating a meshwork that
captures platelets and red blood cells to form a clot. This phase is: Coagulation
2. Collagen fibers are exposed by a break in a blood vessel. Platelets become sticky and cling
to the fibers. They release chemicals to attract more platelets. Eventually they pile up
forming a platelet plug. This phase is: Platelet plug formation
3. Anchored platelets release serotonin which causes blood vessel muscles to
spasm. These spasms contract blood vessels, decreasing blood loss.
This phase is: Vascular Spasms
4. Now put the phases in the correct order:
1. Platelet plug formation
2. Vascular Spasms
3. Coagulation
