Background The endocrine system works with the nervous system to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to specific body parts‚ the endocrine system takes a longer time to produce a longer-lasting effect. The system operates by releasing chemical messengers called hormones into the bloodstream
