Pathophysiology involves the study of functional or physiologic changes in the body
that result from disease processes.
Pathology is the laboratory study of cell and tissue changes associated with disease.

Microorganisms include bacteria, fungi, protozoa, and viruses.
Bacteria are classified as prokaryotic cells because they are very simple in structurelacking even a nuclear membrane but they function metabolically and reproduce.
Many microorganisms are cla
