  3. HUMAN ENDOCRINE SYSTEM 1. 2. 3. 4. 5. Need of Hormones in Human Body Endocrine Glands and Hormones-Definition Human Endocrine System-Glands and Hormones Mechanism of Hormone Action Divisions of Hormones


  4. Need of Hormones in Human Body The neural system provides a point to point rapid coordination among the organs of human body. And these neural coordination is fast but short lived. As the nerve fibers do not innervate all cells of the body and the cellular functions need to be continuously regulated. Therefore, a special kind of coordination and regulation has to be provided. This function is carried out by the hormones. . .The system of hormone producing glands and cells in human body is knowrn as the Endocrine system. This system along with neural system coordinate and regulate the physiological functions in the body.


  5. Endocrine Glands and Hormones-Definition Endocrine gland lack ducts and are hence, called ductless glands. Their secretions are called Hormones Therefore, hormone are chemical produced by endocrine glands and released into the blood and transported to a distantly located targeted organ. In other words, hormones are non-nutrients chemicals which act as intercellular messengers and are produced in trace amounts. Invertebrate possess a very simple endocrine system with few hormones whereas a large number of chemicals act as hormones and provide coordination in the vertebrates.


  6. uman Endocrine System The endocrine glands and hormone producing diffused tissues/cells located in different parts of human body constitute the endocrine system. . The endocrine system constitutes the following 1.Pituitary Gland 2.Pineal Gland 3.Thyroid Gland 4.Adrenal Gland 5. Parathyroid Gland 6. Thymus Gland 7.Gonads (Testis and Ovary) 8.Pancreas


  7. In addition to these, some other organs also produce hormones. These are as 1. Gastrointestinal Tract 2. Liver 3. Kidney 4. Heart
