1.NEGATIVE FEED BACK SYSTEM OF ENDOCRINE SYSTEM
In endocrine system, most of the hormones are regulated by feed back mechanisms.A feedback mechanism is a loop in which a product feeds backs to control its own production. Most hormone feedback mechanisms involve negative feedback loops. negative feedback keeps the concentration of a hormone with in a narrow range.Hormone and production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit further release. In ths way, the concentration of hormones in blood is maintained with in a narrow range.
2. 10 COMMANDMENTS OF TTHE ENDOCRINE SYSTEM
The endocrine system made up of glands that make hormones. Hormone are the chemical mssengers, that carry the information and instructions from one cell to another.
Endocrine glands release hormones in to the blood stream and then it travels in o the other parts of the body.
The endocrine hormone help to control mood,growth and development that is the way our organs work,metabolism and reproduction.
THe endocrine system regulate how much of each hormone is released.
This can depends upon levels of hormone already in the blood.
Many things affect hormone levels,such asstress, infection,a nd changes in the balance of fluids and minerals in blood.
The major glands that make up the endocrine system are the hypothalamus, pituitary, thyroids, parathyroids,adrenals, pineal body,the ovaries and the testes.
