The apex of the heart is the lowest superficial part of the heart. Which option correctly identifies this statement?

• A. The highest part of the heart
• B. The lowest superficial part of the heart
• C. The posterior surface of the heart
• D. The left border of the heart

Answer: (B)

Understanding heart orientation helps you place each part correctly. The apex is the tip of the heart formed mainly by the left ventricle and it points downward and to the left. Because that tip sits closest to the chest wall, it is the most superficial part of the heart and is where you can usually feel the apex beat.

So, the statement that the apex is the lowest superficial part is accurate. The other descriptions refer to other regions: the highest part is near the base where the great vessels are; the posterior surface corresponds to the base of the heart; the left border is formed along the left edge of the heart by the left atrium and ventricle.
