This runs counter to most physiology textbook introductions which tend toward making statements like, "The body's main goal is maintaining homeostasis," and from there framing the rest of the bodily processes as various feedback mechanisms which normally align to achieve homeostasis. Sometimes these processes are at odds with each other, and only their combined effect is homeostatic, but pedagogically the nuance of that is present from the start of education.
