The endocrine system is one of the two systems that are responsible for communication and integration between various body tissues, the other being the nervous system. Endocrine communication is achieved by means of chemical messengers called hormones. Hormones are produced in endocrine glands and secreted into the bloodstream to reach body tissues. A hormone can travel wherever the blood goes, but it can only affect cells that have receptors for it. These are called target cells.
Human endocrine system is a group of ductless glands that regulate body processes by secreting chemical substances called hormones. Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues. Diseases of the endocrine system can result from the over secretion or under secretion of hormones or from the inability of target organs or tissues to respond to hormones effectively.
