,Question 1
A student reviewing cardiac anatomy identifies the valve
located between the left atrium and left ventricle. Which valve
is being described?
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 is between the right ventricle and
pulmonary artery.
• The aortic valve is between the left ventricle and aorta.

Question 2
Blood returning from the lungs enters which chamber of the
heart first?
,A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
Correct Answer: B
Rationale:
Oxygenated blood from the lungs returns through the
pulmonary veins into the left atrium. From there, blood passes
through the mitral valve into the left ventricle.
• The right atrium receives deoxygenated blood from
systemic circulation.
• The ventricles receive blood after atrial filling.

Question 3
A nurse explains that the tricuspid valve prevents blood from
flowing backward into which structure?
A. Pulmonary artery
B. Left atrium
C. Right atrium
D. Aorta
Correct Answer: C
, Rationale:
The tricuspid valve separates the right atrium from the right
ventricle and prevents backflow into the right atrium during
ventricular contraction.
• The pulmonary artery is protected by the pulmonic valve.
• The left atrium is associated with the mitral valve.
• The aorta is associated with the aortic valve.

Question 4
Which sequence correctly describes blood flow through the
heart after blood enters the right atrium?
A. Right atrium → mitral valve → right ventricle → lungs
B. Right atrium → tricuspid valve → right ventricle →
pulmonary artery
C. Right atrium → pulmonic valve → left ventricle → lungs
D. Right atrium → aortic valve → left ventricle → aorta
Correct Answer: B
Rationale:
Blood flows from the right atrium through the tricuspid valve
into the right ventricle and then through the pulmonic valve
into the pulmonary artery toward the lungs.
