Insulin and Glucagon

This lesson explains how blood glucose levels are regulated by insulin and glucagon through a negative feedback system. After consuming carbohydrates, blood glucose levels rise, prompting the pancreas to release insulin, which helps convert glucose to glycogen in the liver and facilitates glucose uptake by body cells. This process lowers blood glucose to optimal levels. Conversely, when blood glucose levels drop, glucagon is released, stimulating glycogen breakdown into glucose, raising blood glucose levels. The video highlights the importance of these hormones in maintaining glucose balance and the implications of system failure, such as diabetes.

Explain the role of the liver in blood glucose regulation.

What medical condition can arise when the blood glucose regulation system is faulty?
