The branch of science that describes the consequences of improper body function is called pathology.

Here's a breakdown:

* Pathology is the study of the causes, mechanisms, and effects of disease. It examines the structural and functional changes that occur in the body during disease.

* Pathophysiology specifically focuses on the functional changes that occur in the body during disease, how these changes affect the body's normal function, and how these changes contribute to the symptoms and complications of disease.

While pathology is a broad field, it encompasses the study of disease and its effects, which includes the consequences of improper body function.
