The liver and the pancreas have a central role in the regulation of blood glucose concentration. The cells in the pancreas secrete the hormones which tell cells to take up glucose from the blood or no
This article describes how blood glucose regulation is an example of negative feedback in the body. Negative feedback is when a body makes a change to maintain homeostasis and then reverses it. An example in the body's glucose regulation when there is too much glucose in the blood, the pancreas releases insulin to be regulated, and when the body reaches homeostasis, the pancreas stops secreting insulin.
This article talks about what key hormones play important roles in regulating blood glucose levels. Insulin is a hormone that regulates blood levels when they increase above homeostasis, it is a key component for people with diabetes. Glucagon is a hormone used to regulate blood glucose when levels decrease to below homeostasis. This hormone prevents low blood sugar and lack of energy.
This article describes the cells that are involved in blood glucose regulation, such as insulin and glucagon and also the roles they play in diabetes. They also describe the processes of glycogenolysis and glycogenesis, or breaking down of glycogen to glucose and the forming of glycogen from glucose.
