1930s biological and psychological circles occasionally used the term to refer to a mental strain or to a harmful environmental agent that could cause illness. Walter Cannon used it in 1926 to refer to external factors that disrupted what he called homeostasis. But "Stress as an explanation of lived experience is absent from both lay and expert life narratives before the 1930s". The use of the term ‘stress’ is now so integrated into our thoughts that it sometimes feels it has always been there. In fact

regulation of GFR and distal salt delivery. The current view is that this mechanism insulates renal excretory function from fluctuations in BP. Indeed‚ the concept that renal autoregulation is necessary for normal renal function and volume homeostasis has long been a cornerstone of renal physiology. This article presents a very different view‚ at least regarding the myogenic component of this response. We suggest that its primary purpose is to protect the kidney against the damaging effects

an organism responds. Characteristics of Living Things Living things maintain a stable internal environment. Although conditions outside an organism may change‚ conditions inside an organism tend to remain constant. This process is called homeostasis.
