Which study focuses on how diseases affect the body?

The study that focuses on how diseases affect the body is pathophysiology. Pathophysiology combines elements of pathology, which is the study of the causes and effects of diseases, with a deeper understanding of physiology, the normal functioning of the body. This discipline examines how diseases disrupt normal physiological processes, leading to changes in function and structure at both the cellular and systemic levels. By understanding these alterations, pathophysiology helps in defining disease mechanisms, identifying symptoms, and formulating appropriate treatments.

The use of this knowledge is essential in clinical settings where practitioners need to understand not just the disease itself, but also its implications for body function and overall health. In contrast, anatomy focuses on the structure of the body, while physiology deals with the normal functions of various body systems. Both of these areas provide foundational knowledge, but they do not specifically address the impact of disease processes as pathophysiology does.
