…showed last 75 words of 1889 total…The hormones controlling the digestive and excretory systems are located some distance away from the cells that they have to control, therefore some method of transport must be utilized. This method is the bloodstream. The hormonal glands secrete their hormones into the bloodstream. These hormones then travel to the target organ or cell, and regulate the activity of that organ or cell. This system is slower to respond than the nervous system.
