- They are the second control system (the first being the nervous system)
- Responses controlled by the nervous system are fast and generally over quickly, but responses controlled by hormones are slow and generally last for a long time

- Hormones are soluble substances made by a number of glands which make up the endocrine system
- The endocrine gland makes hormones and releases them into the bloodstream
- Different hormones are made to trigger different organs
- Most endocrine glands are controlled by the pituitary gland, located at the base of the brain
- For the body to function properly, it needs the correct amount of each hormone
- The master gland (pituitary gland) makes the most hormones and they control and coordinate the other hormones
- Adrenaline prepares the body for action and causes the heart and breathing rate to increase, and directs blood to the muscles
- Testosterone causes sexual development in males and oestrogen causes sexual development in females
