HORMONES & ENDOCRINE SYSTEM Introduction to the endocrine system of hormones including homeostasis and the function of the hormones adrenaline and thyroxine including explaining negative feedback systems (other hormones are dealt with on other pages - see below the sub-index) * Doc Brown's GCSE level biology exam revision study notes * Sub-index for this section on hormones and the endocrine system (1) What are hormones? What do they do? (2) Endocrine system: Examples of hormones and which gland or organ produces them (3) A comparison of the nervous system and the endocrine hormone system (4) The function of the hormone adrenaline (5) The function of the hormone thyroxine See also (6) to (10) in other sections of the website involving homeostasis and hormones Reminder: Homeostasis the function of self-regulating processes by which biological systems (organisms) tend to maintain physical and chemical stability while adjusting to conditions that are optimal for survival i.e. counteracting unfavourable conditions. These process can involve hormones secreted from the glands of the endocrine system. Below are links to the specific sections on homeostasis. (6) Homeostasis: introduction to how it functions (negative feedback systems explained) (7) Homeostasis: control of blood sugar level - insulin and diabetes (8) Homeostasis: osmoregulation, ADH, water/urea/ion control, kidney function, dialysis (9) Hormone systems: menstrual cycle including contraception and fertility treatments (10) Hormone control of plant growth and uses of plant hormones WHERE NEXT?
