Systemic physiological environment

Systemic physiological environment" refers to the collective internal conditions of an organism that arise from the integration and interaction of all major physiological processes at the cellular, organ, and system levels[1][5]. It encompasses the internal milieu regulated by homeostatic mechanisms, such as temperature, pH, osmolarity, metabolic substrates, and signal molecules[1][6]. This environment is maintained by the dynamic and coordinated activity of organ systems—cardiovascular, respiratory, renal, endocrine, nervous, and immune systems—ensuring stable conditions for cellular function and organismal survival, despite external and internal challenges[1][4][5]. The term is not itself a molecular therapeutic target, but provides the functional context in which specific molecular targets operate and is essential for understanding physiological and pathological responses[3][8].
