This article presents an overview of studies, including author's original ones, devoted to the problem of intrinsic (physiological) of biological organisms and integral characteristics of their functioning. Invariance is hypothesized for the entropy action functional, which is a newly introduced physical value for the complex self-organizing system (organisms). The hypothesis suggests that the value of the entropy action functional is the same for all individuals of a particular species. Based on the hypothesis, an interaction was detected between the intrinsic (physiological) and extrinsic (chronological) times that control the growth of a biological organism. The resulting formula for this interaction includes the second entropy differential, which is a fundamental function in Prigogine’s theory of nonequilibrium thermodynamics structure. A fractal structure was shown for intrinsic time of an organism. An equation has been proposed for calculating the deterministic entropy of metabolism as a mathematical measure that makes it possible to test this hypothesis in certain species of organisms. The prospects for testing the hypothesis for organisms are discussed.

本文概述了研究，包括作者的原创研究，致力于生物有机体的内在（生理）问题及其功能的整体特征。熵作用泛函假设了不变性，这是复杂自组织系统（有机体）新引入的物理值。该假设表明熵作用泛函的值对于特定物种的所有个体都是相同的。基于该假设，检测到控制生物有机体生长的内在（生理）时间和外在（时间顺序）时间之间的相互作用。这种相互作用的结果公式包括第二熵微分，这是普里高津非平衡热力学结构理论中的一个基本函数。显示了有机体固有时间的分形结构。已经提出了一个公式来计算代谢的确定性熵，作为一种数学度量，可以在某些生物物种中测试该假设。讨论了检验生物体假设的前景。
