Human physiology – a continuum of balance

Human physiology – a continuum of balance

Physiology is the science concerned with the body functions and its underlying mechanisms. It is one of the basic medical sciences including anatomy, histology, pathology, microbiology and pharmacology. The advantage that physiology could have compared to other basic sciences is that it goes hand in hand with body function, regulation and disturbance. Anyhow, it could be agreed upon that separation of basic sciences may apply only for simplification and study purposes rather than for real and working performances.

Sticking to basics and practical problems it may be quite obvious that medical staff including physicians study physiology in order to care of sick individuals especially those in serious conditions that need timely and efficient management. In this respect the appreciation and mastering of basic body functions that normally work dependent on each other like and for a continuum balance would make the difference in defining certain outcome. That is why studying physiology as a basic medical study course should be precise, focused and appropriately modular. In other words, the objective view and appreciation of the dynamic and interconnected body functions in a working and easily perceived biophysical model could be that what is conceived in memory and helps in health problem solving apart from many apparently irrelevant and superfluous details.

A well known medical term is homeostasis which would mean the fundamental criterion of keeping the body internal environment within a normal range of biochemical and biophysical values in a dynamic steady state. Therefore, homeostasis concludes the ultimate goal of all physiological processes and describes biological and living systems as comprehensively and elegantly as possible. Behind the coulisses of homeostasis one might see several body organs and tissues, each assigned to a certain function, that work dependently in harmony. Again, one may prefer to reduce those functions to their underlying biochemical and biophysical component forces that could be approximated to a couple of laws or mathematical equations. Such preference could be based on both personal views and study or experimental facilities and should accordingly influence medical case management in terms of time, technical issues, costs and ultimately outcome.

As it could be understood from the discussion above, studying physiology outside its pathophysiological frame would be a matter of time waste. This is simply because investigating disease is an essential drive and clue as well to understand a certain normal physiological process (recall the purpose of physiology as basic medical course mentioned earlier in the essay). Accordingly, it may be very rational to establish a general check list or scheme when discussing a given physiological or pathophysiologic question. Such a check list can include body temperature, pulse, blood pressure, pH, electrolytes, general condition, mood, and any emergent complaint. To conclude this essay on human physiology, it signifies the importance of modular systematic physiology and systematic review of its findings and examination.
