The human endocrine system: blood glucose levels

• Hormones are chemical messangers
• Hormones are released by organs called glands into the bloodstream
• The blood carries hormones to their target organs where they produce a specific effect
• The effects of the endocrine system are produced more slowly than the effects of the nervous system.
• However, the effects of the endocrine system last longer than the effects of the nervous system.

• The pituitary gland produces hormones that affect many target organs.
• hormones from the pituitary gland affect the pancreas, thyroid and adrenal glands.
• The pituitary gland can stimulate other glands to release even more hormones.
• The pituitary gland is a "master gland" and is found at the base of the brain “.
• The pancreas is a gland that monitors and controls blood glucose levels
• Insulin causes glucose to move out of the blood and into cells.
• Insulin also causes liver and muscle cells to convert glucose into glycogen.
• Glycogen is a carbohydrate that can be stored for later use
• If blood glucose concentration is too low, the pancreas releases a hormone called glucagon
• -Glucagon causes liver and muscle cells to convert glycogen into glucose.

  -Glucagon causes glucose to move out of cells and into the blood.This raises the level of glucose in the blood.
• Diabetes is a condition where blood glucose levels stay high after eating
• There are two types of diabetes: Type 1 and Type 2.
