Control blood glucose

• What hormones control blood glucose concentration?

  Insulin and glucagon
• What does blood glucose concentration refer to?

  The amount of sugar in the bloodstream
• Why do we need a decent amount of sugar in our blood?

  To provide a constant supply of glucose for respiration
• What happens if blood glucose concentration gets too high?

  It can start to damage our tissues
• What occurs when a person eats a large meal with carbohydrates?

  Blood glucose concentration increases
• How does the pancreas respond to increased blood glucose levels?

  It releases insulin into the bloodstream
• What is the role of insulin in blood glucose regulation?

  It tells cells to take in glucose from the blood
• Which cells are most important for taking up glucose?

  Liver and muscle cells
• What is glycogen?

  A long-term storage form of glucose
• What happens to blood glucose concentration after insulin is released?

  It decreases back to normal levels
• What hormone is released when blood glucose levels drop too low?

  Glucagon
• How does glucagon function in blood glucose regulation?

  It increases blood glucose levels
• What does glucagon do when blood glucose levels are low?

  It breaks down glycogen into glucose
• How do insulin and glucagon work together?

  They create a negative feedback loop
• What happens when glucose levels get too high?

  Insulin is released to lower glucose levels
• What happens when glucose levels drop too low?

  Glucagon is released to raise glucose levels
• Why do blood glucose levels fluctuate rather than remain constant?

  Insulin and glucagon are constantly released
• What is the effect of skipping breakfast on blood glucose levels?

  It can cause blood glucose levels to drop
• What is the pancreas's role in blood glucose regulation?

  It detects glucose levels and releases hormones
• How does the body maintain blood glucose levels?

  Through the release of insulin and glucagon
