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.)
