Complex physiological processes

Definition

Complex physiological processes refer to the intricate and interrelated functions that occur within biological systems, involving multiple organs, tissues, and cellular interactions. These processes are essential for maintaining homeostasis, responding to environmental changes, and supporting overall organismal health. Understanding these processes is crucial for developing models that accurately mimic human biology in research and therapeutic applications.
