Why are the topics of anatomy and physiology difficult to separate?Multiple ChoicePhysiological functions depend on anatomy of structures.Physiological functions in an organism are ongoing.Our understanding of physiology is changing more than our understanding of anatomy.The body parts take up space.

The topics of anatomy and physiology are difficult to separate because physiological functions depend on the anatomy of structures. This means that the way our bodies function (physiology) is directly related to the structure and organization of our bodies (anatomy). For example, the physiology of the heart (how it pumps blood) is directly related to its anatomy (its chambers, valves, and vessels). Therefore, understanding one topic often requires understanding the other, making them difficult to separate.
