Unit 3: Homeostatis
Homeostasis involves maintaining internal stability within the human body through complex feedback systems. The nervous and endocrine systems play crucial roles in this process. The nervous system, comprising the central and peripheral components, transmits electrochemical messages via neurons and glial cells.
