System - The University of Texas at Arlington
(60 questions with answers and brief rationales)
1. The heart is located in the:
A. Right thoracic cavity
B. Mediastinum
C. Abdominal cavity
D. Pleural space
Answer: B
Rationale: The heart lies in the mediastinum, between the lungs.
2. The outermost layer of the heart is the:
A. Endocardium
B. Myocardium
C. Epicardium
D. Pericardium
Answer: C
Rationale: Epicardium is the visceral layer of the serous pericardium, covering the heart
surface.
3. The pericardial sac that surrounds the heart is called the:
A. Endocardium
B. Myocardium
C. Parietal pericardium
D. Epicardium
Answer: C
Rationale: The parietal pericardium is the tough fibrous sac; the visceral pericardium
(epicardium) covers the heart.
4. The thick muscular layer of the heart is the:
A. Endocardium
B. Myocardium
C. Epicardium
D. Pericardium
, Answer: B
Rationale: Myocardium is the cardiac muscle responsible for contraction.
5. Which chamber pumps blood to the lungs?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: B
Rationale: The right ventricle pumps deoxygenated blood to the lungs via the
pulmonary artery.
6. Which chamber pumps oxygenated blood to the body?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Answer: D
Rationale: The left ventricle pumps oxygenated blood into the aorta for systemic
circulation.
7. The tricuspid valve is located between the:
A. Right atrium and right ventricle
B. Left atrium and left ventricle
C. Right ventricle and pulmonary artery
D. Left ventricle and aorta
Answer: A
Rationale: The tricuspid valve separates the right atrium from the right ventricle.
8. The mitral valve is located between the:
A. Right atrium and right ventricle
B. Left atrium and left ventricle
C. Right ventricle and pulmonary artery
D. Left ventricle and aorta
