Hormones are primarily distributed throughout the body via the bloodstream. They bind to specific receptor molecules on the surface or within cells, which allows them to affect certain tissues or cells. This is why hormones are considered to be a form of long-distance communication in the body. Hormones can also be delivered locally through the interstitial fluid, but this is not the primary means of distribution.
