Question: 1 / 400

What is the inferior portion of the ventricles of the heart called?

apex

The inferior portion of the ventricles of the heart is called the apex. The apex is specifically the tip of the heart formed by the left ventricle, and it points down and to the left. This structure plays a crucial role in the heart's function, as it is where the strongest part of the heart's muscular wall is located, allowing for effective pumping of blood to the body.

The base, in contrast, refers to the broader, upper portion of the heart where major blood vessels enter and exit. The septum is the wall that separates the right and left sides of the heart, preventing the mixing of oxygen-rich and oxygen-poor blood. Dorsum is not a term typically used in the context of heart anatomy; it's more related to positioning or another field, such as anatomy of the back in general. Thus, the apex is the correct term to describe the inferior region of the ventricles.
