These systems control the compensatory mechanisms: hypothalamus - governs or controls the system (cid:1) hunger is an anomaly. However, all of them (heat, hunger, etc) work to maintain homeostasis. The primary drives: thirst and hunger (cid:1) primary drive - stems from unlearned moives to saisfy biological needs (cid:1) saisied through relexive compensatory mechanisms coupled with directed behaviour (cid:1) ex.
