(a) Hemoglobin
(b) Fibrinogen
(c) Platelets
(d) Plasma
Correct Answer: (b)

6. What is the name of the test that is used to determine blood type?
(a) Blood typing
(b) Hemoglobin test
(c) Platelet count
(d) White blood cell count

7. What is the name of the condition in which the body produces too many white blood cells?
(a) Leukemia
(b) Anemia
(c) Thrombocytosis
(d) Hemophilia
Correct Answer: (a)
Explanation: Leukemia is a cancer of the blood cells. In leukaemia, the body produces too many white blood cells, which can crowd out the other types of blood cells.
8. What is the name of the condition in which the body produces too few red blood cells?
(a) Anemia
(b) Leukemia
(c) Thrombocytosis
(d) Hemophilia
Correct Answer: (a)
Explanation: Anemia is a condition in which the body does not produce enough red blood cells. This can lead to fatigue, shortness of breath, and pale skin.
9. What is the name of the condition in which the body produces too many platelets?
(a) Thrombocytosis
(b) Leukemia
(c) Anemia
(d) Hemophilia
Correct Answer: (a)
Explanation: Thrombocytosis is a condition in which the body produces too many platelets. Platelets are blood cells that help the blood clot. When there are too many platelets, they can form clots that can block blood vessels and lead to serious health problems.
10. What is the name of the condition in which the blood vessels become clogged with plaque?
(a) Atherosclerosis
(b) Leukemia
(c) Anemia
(d) Hemophilia
Correct Answer: (a)
Explanation: Atherosclerosis is a condition in which the walls of the arteries become clogged with plaque. Plaque is a fatty substance that can build up over time. When plaque builds up, it can narrow the arteries and make it difficult for blood to flow. This can lead to heart disease, stroke, and other health problems.
In conclusion, increasing awareness about blood-related topics is crucial for fostering a healthier and more informed society. This blood quiz serves as a powerful tool to spread awareness about various aspects of blood, including its composition, functions, and importance in medical treatments.
