What term describes the study of an entire system within the body?

The term that describes the study of an entire system within the body is systemic anatomy. This branch of anatomy focuses on understanding how the various systems of the body, such as the circulatory, respiratory, or nervous systems, function as integrated wholes. By examining these systems in their entirety, one can gain insight into how different organs and structures work together to maintain overall bodily functions.

For instance, when studying the cardiovascular system, systemic anatomy involves learning about the heart, blood vessels, and blood, as well as how these components interact and contribute to overall circulation and health. This approach contrasts with regional anatomy, which looks at specific areas of the body, while microscopic anatomy and surface anatomy focus on structures that are either too small to see with the naked eye or visible on the body's surface, respectively. Understanding systemic anatomy is essential for comprehending how body systems interrelate and support one another in maintaining homeostasis.
