1. Which chamber of the heart receives deoxygenated blood from the body?
A. Left atrium
B. Left ventricle
C. Right atrium
D. Right ventricle
Correct Answer: C
Rationale: The right atrium receives deoxygenated blood through the superior and inferior
vena cava.
2. Which chamber pumps deoxygenated blood to the lungs?
A. Left ventricle
B. Right ventricle
C. Left atrium
D. Right atrium
,Correct Answer: B
Rationale: The right ventricle pumps blood through the pulmonary artery to the lungs.
3. Which chamber pumps oxygenated blood into the aorta?
A. Left ventricle
B. Right ventricle
C. Right atrium
D. Left atrium
Correct Answer: A
Rationale: The left ventricle pumps oxygen-rich blood into systemic circulation.
4. Which blood vessel carries oxygenated blood from the lungs to the heart?
A. Pulmonary artery
B. Superior vena cava
C. Pulmonary vein
D. Inferior vena cava
Correct Answer: C
Rationale: Pulmonary veins carry oxygenated blood to the left atrium.
5. Which valve is located between the right atrium and right ventricle?
A. Mitral valve
B. Aortic valve
C. Tricuspid valve
,D. Pulmonary valve
Correct Answer: C
Rationale: The tricuspid valve prevents backflow into the right atrium.
6. Which valve prevents backflow from the aorta into the left ventricle?
A. Pulmonary valve
B. Tricuspid valve
C. Mitral valve
D. Aortic valve
Correct Answer: D
Rationale: The aortic valve ensures one-way blood flow into systemic circulation.
7. The normal pacemaker of the heart is the:
A. AV node
B. Bundle of His
C. SA node
D. Purkinje fibers
Correct Answer: C
Rationale: The sinoatrial (SA) node initiates the heartbeat.
8. The atrioventricular (AV) node functions to:
A. Pump blood
B. Delay electrical impulses before ventricular contraction
, C. Oxygenate blood
D. Produce hormones
Correct Answer: B
Rationale: The AV node briefly delays conduction to allow ventricular filling.
9. Which blood vessels carry blood away from the heart?
A. Veins
B. Venules
C. Arteries
D. Capillaries
Correct Answer: C
Rationale: Arteries transport blood away from the heart.
10. Which vessels are the smallest blood vessels?
A. Veins
B. Arteries
C. Capillaries
D. Venules
Correct Answer: C
Rationale: Capillaries allow exchange of gases, nutrients, and wastes.
11. Which blood component transports oxygen?
A. Plasma
