Where is the mitral valve located?

• A. Between the right atrium and right ventricle
• B. Between the left atrium and left ventricle
• C. Between the right atrium and left atrium
• D. Between the left ventricle and the aorta

Answer: (B)

The mitral valve is the left-sided atrioventricular valve, located between the left atrium and the left ventricle. It opens to allow blood from the left atrium to fill the left ventricle during diastole and closes during systole to prevent backflow into the atrium. Its counterpart on the right is the tricuspid valve (between the right atrium and right ventricle), while the aortic valve sits between the left ventricle and the aorta. For this question, the correct location is between the left atrium and left ventricle.
