Why are physiology and anatomy frequently studied together?

Anatomy and physiology are often studied together because they are closely related. Anatomy is the study of the structure of living organisms, while physiology is the study of how those structures function1. Understanding the structure of an organism is important because it helps us understand how it works. For example, knowing the structure of the heart helps us understand how it pumps blood through the body. Similarly, understanding how an organism works can help us understand its structure. For example, studying how the heart pumps blood can help us understand its structure.
