Question 1
How many chambers are in the heart?
A. 2 (1 atria, 1 ventricle)
B. 4 (2 atria, 2 ventricles)
C. 3 (2 atria, 1 ventricle)
D. 6 (3 atria, 3 ventricles)
CORRECT ANSWER
B. 4 (2 atria, 2 ventricles)
RATIONALE
• The heart has four chambers: right atrium, right ventricle, left atrium, left ventricle.
• Atria receive blood; ventricles pump blood out of the heart.
• The right side pumps deoxygenated blood to lungs; left side pumps oxygenated blood to body.
, Question 2
Select the best description of the tricuspid valve:
A. Left semilunar valve
B. Right atrioventricular valve
C. Left atrioventricular valve
D. Right semilunar valve
CORRECT ANSWER
B. Right atrioventricular valve
RATIONALE
• The tricuspid valve is located between the right atrium and right ventricle.
• It has three cusps and prevents backflow of blood from the right ventricle into the right atrium.
• Closure of the tricuspid valve contributes to the S1 heart sound ("lub").
Question 3
The function of the pulmonic valve is to:
A. Divide the left atrium and left ventricle
B. Guard the opening between the RA and RV
C. Protect the orifice between the RV and the pulmonary artery
D. Guard the entrance to the aorta from the left ventricle
CORRECT ANSWER
C. Protect the orifice between the RV and the pulmonary artery
RATIONALE
• The pulmonic valve is a semilunar valve located between the right ventricle and pulmonary artery.
• It prevents backflow of blood into the right ventricle during diastole.
• Closure of the pulmonic valve contributes to the S2 heart sound ("dub").
