1. Which blood component is primarily responsible for oxygen
transport?
A. Plasma
B. White blood cells
C. Red blood cells
D. Platelets
Correct Answer: C
Rationale: Red blood cells contain hemoglobin, which binds and
transports oxygen to tissues.
2. Hemoglobin is composed of:
A. Lipids and sugars
B. Globin proteins and heme groups
C. DNA and RNA
D. Platelets and fibrin
Correct Answer: B
,Rationale: Each heme group binds one oxygen molecule, allowing
efficient oxygen transport.
3. The main function of white blood cells is:
A. Transport oxygen
B. Blood clotting
C. Immune defense
D. Carry nutrients
Correct Answer: C
Rationale: WBCs identify and destroy pathogens and abnormal
cells.
4. Platelets are essential for:
A. Gas exchange
B. Blood clotting
C. Hormone transport
D. Nutrient absorption
Correct Answer: B
Rationale: Platelets aggregate at injury sites to form a temporary
clot.
5. Plasma contains:
A. Water, proteins, electrolytes, and nutrients
B. Red blood cells only
C. White blood cells only
,D. Platelets only
Correct Answer: A
Rationale: Plasma transports hormones, nutrients, and waste
products throughout the body.
6. Erythropoiesis occurs in:
A. Liver only
B. Bone marrow
C. Spleen only
D. Lymph nodes only
Correct Answer: B
Rationale: Bone marrow produces red blood cells under the
stimulation of erythropoietin.
7. Which hormone stimulates red blood cell production?
A. Insulin
B. Erythropoietin
C. Glucagon
D. Thyroxine
Correct Answer: B
Rationale: Erythropoietin is secreted by the kidneys in response to
low oxygen levels.
8. Which type of white blood cell produces antibodies?
, A. Neutrophils
B. B lymphocytes
C. Monocytes
D. Eosinophils
Correct Answer: B
Rationale: B cells differentiate into plasma cells that secrete
antibodies.
9. Neutrophils primarily function to:
A. Produce antibodies
B. Phagocytize bacteria
C. Carry oxygen
D. Form clots
Correct Answer: B
Rationale: Neutrophils are the first responders to bacterial
infections.
10. Eosinophils are involved in:
A. Allergic reactions and parasitic infections
B. Oxygen transport only
C. Blood clotting only
D. Hormone production only
Correct Answer: A
Rationale: Eosinophils release enzymes that combat parasites and
mediate allergic responses.
