How is the etiology of a disease linked to its pathophysiology?

In: 1

Answer 1

Etiology is the underlying cause for disease. Pathophysiology is the description of the disordered systems.

For example, you can have a disorder which affects your ability to clot blood called Hemophilia A. The etiology of Hemophilia A is the genetic loss of code that programs for a particular step in body’s ability to clot. The pathophysiology of Hemophilia A describes the clotting cascade, identifies the missing factor, and illustrates the results.
