Fysiologisin

Fysiologisin is a term occasionally encountered in contemporary physiology discourse to denote an integrative approach to studying living systems. In this usage, fysiologisin refers to the emphasis on dynamic interactions among physiological subsystems—nervous, hormonal, cardiovascular, respiratory, and metabolic—rather than treating them as isolated pathways. The term is not part of a formal subdiscipline, and its usage varies by language and author; in many cases it overlaps with established concepts such as integrative physiology or systems physiology.

Key ideas associated with fysiologisin include systems-level modeling, homeostatic regulation across scales, network perspectives, experimental designs that measure multiple endpoints simultaneously, computational simulations, and cross-disciplinary collaboration with systems biology and bioinformatics.

Applications of the concept span the study of how stress influences cardiovascular and metabolic regulation, sleep-wake and autonomic control, exercise physiology, and disease states where multisystem interactions are central, such as sepsis and metabolic syndrome. By focusing on interdependencies among bodily systems, fysiologisin aims to provide a holistic view of physiological function rather than a collection of isolated mechanisms.

Criticism and status: some scholars view fysiologisin as redundant with existing terms, while others consider it a useful emphasis for highlighting interdependence among bodily systems. It has limited formal recognition in major textbooks, and rigorous standards of evidence align with those of other physiological fields. Related concepts include integrative physiology, systems biology, and homeostasis.
