The main theme in this unit is to develop an understanding of the hormone system and the endocrine glands. You will be looking at the principles behind homeostasis and feedback mechanisms involved such as blood sugar control. You will also look at the actions of hormones and the understandings of molecular processes in steroid and peptide action. You will be illustrating and giving accounts of the endocrine system and identifying the specific organs associated with the system. There will be an opportunity to discuss the medical use of synthetic hormones such as HRT.
