1. The primary function of the cardiovascular system is to:
A. Produce hormones
B. Digest food
C. Transport substances throughout the body
D. Control movement
Answer: C. Transport substances throughout the body
Rationale: The cardiovascular system transports oxygen, nutrients, hormones, and
wastes through the blood.
2. The main organ responsible for pumping blood is the:
A. Lung
B. Kidney
C. Heart
D. Liver
Answer: C. Heart
Rationale: The heart contracts rhythmically to pump blood through the circulatory
system.
,3. The chamber of the heart that receives oxygenated blood from the lungs is
the:
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: C. Left atrium
Rationale: The left atrium receives oxygen-rich blood from the pulmonary veins.
4. The chamber of the heart that pumps blood to the body is the:
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: D. Left ventricle
Rationale: The left ventricle pumps oxygenated blood into systemic circulation.
5. The valve between the left atrium and left ventricle is the:
A. Tricuspid valve
B. Pulmonary valve
C. Aortic valve
D. Mitral valve
Answer: D. Mitral valve
Rationale: The mitral valve prevents backflow of blood from the left ventricle into
the left atrium.
6. The valve between the right atrium and right ventricle is the:
,A. Aortic valve
B. Mitral valve
C. Tricuspid valve
D. Pulmonary valve
Answer: C. Tricuspid valve
Rationale: The tricuspid valve controls blood flow between the right atrium and
right ventricle.
7. The natural pacemaker of the heart is the:
A. AV node
B. Bundle branches
C. Purkinje fibers
D. Sinoatrial (SA) node
Answer: D. Sinoatrial (SA) node
Rationale: The SA node generates electrical impulses that initiate heart
contractions.
8. The blood vessel that carries blood away from the heart is an:
A. Vein
B. Capillary
C. Artery
D. Venule
Answer: C. Artery
Rationale: Arteries transport blood away from the heart under high pressure.
9. The blood vessel responsible for exchange of gases and nutrients is the:
A. Artery
B. Vein
, C. Capillary
D. Aorta
Answer: C. Capillary
Rationale: Capillaries have thin walls that allow exchange between blood and
tissues.
10. Veins primarily transport blood:
A. Away from the heart
B. To the lungs only
C. Toward the heart
D. Into arteries
Answer: C. Toward the heart
Rationale: Veins return blood from tissues back to the heart.
11. The largest artery in the human body is the:
A. Pulmonary artery
B. Carotid artery
C. Femoral artery
D. Aorta
Answer: D. Aorta
Rationale: The aorta receives blood from the left ventricle and distributes it
throughout the body.
12. The oxygen-carrying protein in red blood cells is:
A. Albumin
B. Fibrin
C. Hemoglobin
D. Insulin
