Which statement about the apex of the heart is true?

• A. It is the inferior point formed by the tip of the left ventricle
• B. It is the superior point formed by the base of the right ventricle
• C. It is located near the spleen
• D. It is the site where the coronary arteries originate

Answer: (A)

The apex is the inferior tip of the heart formed by the left ventricle. It points toward the left side of the chest and lies around the left 5th intercostal space at the midclavicular line, which is where you can usually feel the point of maximal impulse. This explains why the statement about the apex being the inferior point formed by the tip of the left ventricle is true. The base of the heart, by contrast, is the superior portion formed mainly by the atria, not the right ventricle. The apex is not near the spleen, which sits in the left upper quadrant of the abdomen. And the coronary arteries originate from the aortic sinuses at the base of the heart, not at the apex.
