In physiological terms, what does "physiologic" pertain to?

The term "physiologic" specifically pertains to processes related to body functions and the normal mechanisms by which living organisms operate. This includes the study of how various body systems function, how different organs interact with one another, and how physiological processes contribute to overall health and disease. By focusing on the functions and activities of cells, tissues, and organs in a living organism, "physiologic" encompasses a broad range of biological activities vital for maintaining homeostasis and responding to internal and external stimuli.

The other options focus on different aspects: external environments relate to the ecological or environmental context, medicinal effects pertain to pharmacology and how drugs influence the body, and psychological functions are aligned with mental processes and behaviors. Each of these areas is essential in its own right but does not define the term "physiologic," which is specifically rooted in bodily functions.
