Review of Related Diseases (RRD) 1 Practice Exam

The main idea here is distinguishing terms that describe how living bodies work under normal conditions from terms that describe disease, regulation, or coexisting conditions. Physiologic relates to the normal functioning of living organisms and their systems. It covers how organs, tissues, and cells operate together when there isn’t disease or injury—things like normal heart function, digestion, and hormonal signaling. In contrast, pathologic refers to disease or abnormal states, comorbidity means having additional diseases at the same time, and homeostasis describes the body's ongoing effort to keep internal conditions stable. So the term that best captures the idea of normal functioning is physiologic.
