blood glucose levels/adrenaline

• adrenaline is produced by adrenal glands
• adrenaline is also known as epinephrine
• adrenaline triggers the "fight or flight" response
• effects of adrenaline:

  • heart rate increases
  • blood vessels contract
  • air passages dilate
• the adrenaline response is triggered by the sympathetic nervous system
• the release of adrenaline is triggered by events that involve danger or high stress
• glucose: type of sugar that provides energy for your body (through cellular respiration)
• if your body has too LITTLE glucose: you will have feelings of dizziness

  if your body has too MUCH glucose: it will make your blood thick and it'll move slowly
• glucose is a simple sugar that is water soluble and floats freely in blood
• glycogen is a complex sugar - the stored form of glucose - that is insoluble in water. they are NOT hormones
• blood glucose levels = BGL
• diabetes is associated with blood glucose levels
• when BGL are high, insulin is released by the pancreas and glucose is converted to glycogen
• when BGL are low, glucose is released by the liver
• insulin: a hormone produced in the pancreas. regulates the amount of glucose in the blood
• glucagon is a hormone that triggers your liver to convert glycogen into glucose
