function of endocrine system

• Endocrine system


  A system in the body that works alongside the nervous system, made up of a network of specialist glands that release chemical messengers called hormones
• Endocrine system


  • Hormones transmit information via the blood stream
  • Some chemicals can be both a neurotransmitter and hormone depending on the task and location
• Function of the endocrine system

  To secrete hormones needed to regulate many bodily functions and provide a chemical system of communication via the blood stream
• Regulation of the endocrine system

  The hypothalamus exerts its influence through its effect on the pituitary gland
• Endocrine glands and their main hormones

  • Pineal gland - Melatonin
  • Adrenal medulla - Adrenaline and noradrenaline
  • Adrenal cortex - Glucocorticoids (such as cortisone, cortisol and corticosterone)
• Melatonin


  • Regulation of arousal, biological rhythms and the sleep-wake cycle
• Adrenaline and noradrenaline


  • Fight or flight response, increased heart rate and blood flow to the brain and muscles, release of stored glucose and fats for use
• Glucocorticoids


  • Further release of stored glucose and fats for energy expenditure, suppression of the immune system and the inflammatory response

• Endocrine system


  • Hormones transmit information via the blood stream
  • Some chemicals can be both a neurotransmitter and hormone depending on the task and location
• Function of the endocrine system

  To secrete hormones which are needed to regulate many bodily functions and to provide a chemical system of communication via the blood stream
• Hypothalamus


  Regulates the endocrine system through its effect on the pituitary gland
