Endocrine system Endocrinology is the study of chemical communication systems that provide the means to control a huge number of physiologic processes. Like other communication networks‚ endocrine systems contain transmitters‚ signals and receivers that are called‚ respectively‚ hormone producing cells‚ hormones and receptors. The first step in understanding endocrinology is to explore the meaning of such terms as hormone‚ receptor and target cell‚ and to obtain an understanding of how chemical

of well known environmental contaminants‚ such as dioxin‚ PCBs and DDT‚ can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs.

ENDOCRINE SYSTEM The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Endocrine glands do not have a duct system and are called ductless glands. These glands release hormones directly into the blood or lymph. These glands include the pituitary gland‚ the pineal gland
