1. Which chamber of the heart pumps oxygenated blood to the body?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
Correct Answer: D
Rationale: The left ventricle has the thickest wall and pumps oxygenated blood through the
aorta to the systemic circulation.
2. Which blood vessel carries oxygenated blood away from the heart?
A. Pulmonary artery
B. Superior vena cava
C. Aorta
D. Inferior vena cava
,Correct Answer: C
Rationale: The aorta is the largest artery and distributes oxygen-rich blood to the body.
3. Which heart valve is located between the left atrium and left ventricle?
A. Tricuspid valve
B. Pulmonary valve
C. Mitral (bicuspid) valve
D. Aortic valve
Correct Answer: C
Rationale: The mitral valve prevents backflow into the left atrium during ventricular
contraction.
4. The normal pacemaker of the heart is the:
A. AV node
B. Bundle of His
C. Purkinje fibers
D. Sinoatrial (SA) node
Correct Answer: D
Rationale: The SA node initiates the electrical impulses that regulate heart rhythm.
5. Which blood vessels carry blood back to the heart?
A. Arteries
B. Arterioles
,C. Veins
D. Capillaries
Correct Answer: C
Rationale: Veins return blood to the heart and often contain valves to prevent backflow.
6. Which blood vessels are the primary site of nutrient and gas exchange?
A. Arteries
B. Veins
C. Capillaries
D. Venules
Correct Answer: C
Rationale: Capillary walls are only one cell thick, allowing efficient exchange.
7. Which blood cells transport oxygen?
A. White blood cells
B. Platelets
C. Red blood cells
D. Plasma cells
Correct Answer: C
Rationale: Red blood cells contain hemoglobin, which binds oxygen.
8. Which blood cells are primarily responsible for fighting infection?
A. Erythrocytes
, B. Leukocytes
C. Platelets
D. Plasma proteins
Correct Answer: B
Rationale: Leukocytes protect the body against pathogens.
9. Platelets are primarily responsible for:
A. Oxygen transport
B. Hormone production
C. Blood clotting
D. Antibody production
Correct Answer: C
Rationale: Platelets initiate clot formation following blood vessel injury.
10. Which plasma protein is mainly responsible for maintaining blood osmotic
pressure?
A. Hemoglobin
B. Albumin
C. Fibrin
D. Myosin
Correct Answer: B
Rationale: Albumin helps maintain blood volume by regulating osmotic pressure.
