1. What is the primary function of blood in the human body?
A. Signal transmission
B. Hormone production
C. Transport of nutrients and gases
D. Muscle contraction
Correct answer: C
Rationale: Blood transports oxygen, carbon dioxide, nutrients, and
waste throughout the body.
2. Which component of blood is responsible for oxygen transport?
A. White blood cells
B. Platelets
C. Red blood cells
D. Plasma
,Correct answer: C
Rationale: Red blood cells contain hemoglobin, which binds and
carries oxygen.
3. What is the main function of white blood cells?
A. Clotting
B. Immune defense
C. Oxygen transport
D. Hormone regulation
Correct answer: B
Rationale: White blood cells fight infections and provide immunity.
4. Which plasma protein is primarily responsible for maintaining
osmotic pressure?
A. Fibrinogen
B. Albumin
C. Globulin
D. Hemoglobin
Correct answer: B
Rationale: Albumin regulates blood volume by controlling osmotic
pressure.
5. What is the function of platelets?
,A. Oxygen transport
B. Blood clotting
C. Immune defense
D. Nutrient transport
Correct answer: B
Rationale: Platelets aggregate at injury sites to form clots.
6. Which type of white blood cell produces antibodies?
A. Neutrophils
B. Lymphocytes
C. Monocytes
D. Eosinophils
Correct answer: B
Rationale: B-lymphocytes produce antibodies to target pathogens.
7. Which white blood cell is the first responder to bacterial
infection?
A. Neutrophils
B. Lymphocytes
C. Monocytes
D. Eosinophils
Correct answer: A
Rationale: Neutrophils are abundant and phagocytize bacteria
during early infection.
, 8. What is the main component of plasma?
A. Water
B. Protein
C. Lipids
D. Cells
Correct answer: A
Rationale: Plasma is about 90% water and carries nutrients,
hormones, and waste.
9. Which type of blood cell is anucleated in humans?
A. Red blood cell
B. White blood cell
C. Platelet
D. Lymphocyte
Correct answer: A
Rationale: Mature red blood cells lack nuclei to maximize
hemoglobin storage.
10. Which plasma protein is essential for blood clotting?
A. Fibrinogen
B. Albumin
C. Globulin
D. Hemoglobin
