PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The endocrine system consists of: Glands located throughout the body; Hormones made by the glands and released into the bloodstream or the fluid surrounding cells; and. Receptors in various organs and tissues that recognize and respond to the hormones.

Detailed explanation-3: -Endocrine hormone are secreted into the blood and carried by blood and tissue fluids to the cells they act upon, while exocrine hormones are secreted into a duct, and then into the bloodstream. Exocrine hormones are transferred from cell to cell by diffusion (paracrine signaling).
