What type of study would focus on the anatomy of the heart alone?

The type of study that would focus specifically on the anatomy of the heart is system anatomy. System anatomy examines specific organ systems within the body, and in this case, the cardiovascular system, which includes the heart and blood vessels, would be the focus.

This approach allows for an in-depth understanding of how the heart functions within the larger context of the circulatory system, including aspects like the heart's structure, the relationships between different parts of the cardiovascular system, and how these components work together to facilitate blood circulation.

Other approaches, such as regional anatomy, focus on particular areas of the body and may cover multiple systems, which would not provide the same specific concentration on the heart alone. Microscopic anatomy deals with structures that can only be seen with a microscope, such as tissues and cells, which wouldn't allow for a broad understanding of the heart itself. Surface anatomy involves studying landmarks on the body surface and their relation to deeper structures, which again does not specifically address the internal anatomy of the heart in detail.
