From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.

Detailed explanation-2: -Hormones are the chemical signaling molecules produced by the endocrine glands and secreted directly into the bloodstream. They travel through the blood to distant tissues and organs, where they can bind to specific cell sites called receptors.
