,Question 1
A cardiac monitoring student reviews the pathway of blood
flow through the heart. Which structure receives deoxygenated
blood directly from the superior and inferior vena cava?
A. Left atrium
B. Right atrium
C. Right ventricle
D. Pulmonary artery
Correct Answer: B
Rationale:
The superior and inferior vena cava return deoxygenated blood
from systemic circulation directly into the right atrium. Blood
then flows through the tricuspid valve into the right ventricle.
• The left atrium receives oxygenated blood from the
pulmonary veins.
• The right ventricle pumps blood into the pulmonary artery.
• The pulmonary artery carries blood away from the right
ventricle to the lungs.

Question 2
,An ECG learner studies cardiac valve function while reviewing
cardiac anatomy. Which valve separates the left atrium from
the left ventricle?
A. Tricuspid valve
B. Pulmonic valve
C. Mitral valve
D. Aortic valve
Correct Answer: C
Rationale:
The mitral valve, also called the bicuspid valve, is located
between the left atrium and left ventricle. It prevents backflow
of blood into the left atrium during ventricular contraction.
• The tricuspid valve is located on the right side of the heart.
• The pulmonic valve separates the right ventricle from the
pulmonary artery.
• The aortic valve separates the left ventricle from the aorta.

Question 3
A patient’s cardiac anatomy diagram shows blood leaving the
right ventricle. Into which vessel does blood flow next?
, A. Aorta
B. Pulmonary artery
C. Pulmonary vein
D. Coronary sinus
Correct Answer: B
Rationale:
Blood leaving the right ventricle passes through the pulmonic
valve into the pulmonary artery for transport to the lungs.
• The aorta receives blood from the left ventricle.
• Pulmonary veins return oxygenated blood to the left
atrium.
• The coronary sinus drains venous blood from the
myocardium into the right atrium.

Question 4
A telemetry student reviews the sequence of pulmonary
circulation. After blood becomes oxygenated in the lungs,
where does it travel next?
A. Right atrium
B. Right ventricle
