Explanation: 

Detailed explanation-1: -Each hormone acts upon only those cells which have specific receptors. The cells which are acted upon by hormones are called target cells.

Detailed explanation-2: -Paracrine, autocrine and synaptic are three types of local hormone signaling. In paracrine signaling, hormones are released into the fluid between cells (the interstitial fluid) and diffuse to nearby target cells.

Detailed explanation-3: -Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. 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.
