Detailed explanation-1: -In long-distance endocrine signaling, signals are produced by specialized cells and released into the bloodstream, which carries them to target cells in distant parts of the body. Signals that are produced in one part of the body and travel through the circulation to reach far-away targets are known as hormones.

Detailed explanation-2: -Endocrine signaling is an example of long distance communication between hormone producing cells, tissues and glands and cells that express hormone receptor molecules.

Detailed explanation-3: -Yes, endocrine signaling is an example of long-distance signaling. Specialized cells, tissues, glands, and organs use the circulatory system to send the hormones they produce in order to target cells in other parts of the body. It produces a slow and long-lasting response in these target cells.

Detailed explanation-4: -It peaks at 4-12 hours, and can last 12-18 hours.

Detailed explanation-5: -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.
