Since physiology is near and dear to my heart, I thought I’d quickly post a quote that caught my attention from a blog on “What is Physiology?”
Physiological processes are dynamic processes that aim at preserving a constant physical and chemical internal environment. This is an important point. Physiology is much about regulation, that is, closed-loop control systems.
Closed-loop systems – that’s the 30,000-foot view, the starting point for describing the complex moving parts that make the systems work. Communicating the details, the cellular signaling, the transcriptional regulators, the gene promoter elements, that together keep the closed-loop physiological systems balanced (or, on the other hand, what happens when one of the moving parts goes wonky) - that’s the challenge I relish as a science writer and editor.
