Through chemical messengers controlled by a negative feedback system.
Hormones travel from endocrine glands through bloodstream to target organs.
The endocrine system produces hormones which usually travel by way of the blood. Some don't have to travel very far and just diffuse through the tissues.
Hormones of the endocrine glands.
The hormones produced by the endocrine glands are secreted directly into the bloodstream. The circulatory system then distributes these chemical messengers to target tissues throughout the body.

The circulatory system circulates fluids through your body. The endocrine system controls growth and body processes through the use of chemical messengers called hormones.
The traditional approach is that human and animal hormones are produced in endocrine glands, which release them directly into blood, and the bloodstream carries them to their target cells. However, it doesn't necessarily have to be blood, it can be tissue fluid as well. (And not all organisms that have hormones have blood either. In plants for example, hormones can migrate to other cells from the site of production through the plasmodesmata that connect neighboring cells.)

Because an endocrine glad does not have a tube through which it delivers hormone to the body. They just release their hormones into the space around the gland, which diffuse into the blood stream.
