What field of study does anatomy relate to?

Anatomy is the branch of biology that focuses specifically on the study of the structure of organisms, including their systems, organs, and tissues. By examining how the various parts of the body are organized and how they function together, anatomy provides a foundational understanding of living organisms. This field is essential for medical sciences, as it forms the basis for understanding human and animal biology as well as the relationships between different anatomical structures.

The other options relate to entirely different fields. The study of plants pertains to botany, the study of environmental systems involves ecology, and the study of animal behavior is known as ethology. While these fields are interconnected in biological studies, they do not encompass the specific focus of anatomy.
