Pathology TECHNICALLY is just histology of bad stuff.
What most Pathology courses are in most medical school, especially if you have the 1st year - 2nd year model (opposed to the one-organ-system-at-a-time for two year model), is a Mechanism of Disease course.
Mechanisms of Disease implies etiologies, epidemiology, pictures of pathology, and how it affects the patients. This is pathophys. Most schools never actually blend physiology with pathophys, except to say that the principles you learned in physiology may come up in path.
For example, in path, you arent going to say things like in heart failure, you are at point B on the Frank Starling curve, and therefore cardiac output is low. What you might say is that the dilation of the cardiac muscles leads to a weak and floppy heart, impairing cardiac function. They both say the same thing.
I wouldnt worry too much about it. Unless you are a concrete memorizer and can only remember facts in a book without any synthesis, while learning "Path" you will actually be learning "Pathophys" and even a little bit of "how to do medicine."
FYI: The field of pathology is NOT mechanism of disease. It is staining slides and looking at them. It is histology of bad stuff. Thats it. Dark rooms and microscope slides, stains, and hopefully pandora/slacker radio.
