Controlling Glucose Blood Concentration

• What type of structures secrete hormones: Glands
• Blood Glucose concentration is controlled by hormones: insulin and glucagon.

  
• If Blood glucose concentration is too high it can damage our tissues.

  
• Glycogen is a long term storage form of Glucose.
• Glucagon is a hormone, Glycogen is a large molecule of lots of glucose.
• When there are low levels of blood glucose concentration: the pancreas release glucagon into the blood. It goes to cells. Cells break down Glycogen into small glucose molecules again.
• Insulin is a hormone produced in the prancreas, and is released when the blood glucose concentration is too high.
• Glucagon is a hormone produced in the prancreas, and is released when the blood glucose concentration is too low.
• The Pancreas releases insulin, which bind to recepetors, telling the cells to take the glucose in the blood.

  
• Pancreas secrets Glucagon into the blood to LIVER CELLS, when blood conc is too LOW.
• Gluagon - Glycogen to Glucose. Glucose then diffuses into blood.
• Insulin - Glucose to Glycogen.
• When we eat food containing carbohydrates, it increases our blood glucose concentration.
• When we excersize it removes glucose from our blood for respiration.
