Now look at this image of the endocrine system. This system works differently from the nervous system. Instead of fast signals, it uses hormones—chemical messengers. These hormones travel through the blood and control slower processes. For example, your growth, mood changes, and development during teenage years are controlled by hormones. So while the nervous system works quickly for immediate responses, the endocrine system works slowly but has long-lasting effects.
