Negative feedback loops have an average (normal range) in which your body can function well. If it hits any of the extremes, your body works to. Think about it like a thermostat system for your house. Integrating centre: to coordinate: sensor: constant monitoring, response system: to changes, most feedback systems operate in a negative feedback manner. Basic endocrine dys- functions: hyper-function : too much hormone, hypo-function : too little hormone, resistance : too little effect. This means your hor(cid:373)o(cid:374)es are(cid:374)"t (cid:449)orki(cid:374)g properly, and they are key to the endocrine system. Endocrine gland: a tissue which releases (secretes) a substance into the blood stream; the substance then travels via blood to influence a target cell: makes hormone.
