NUR 229 Lecture Notes - Lecture 27: Blood Sugar, Texas State Highway Loop 1, Glycogen
Document Summary
Sugar (body needs it to survive) fuels the cells of your body so they can work properly, but it can not enter the cell without the help. It is stored mainly in the liver in the form of glycogen. Deals with high blood sugar levels : a hormone that helps regulate the amount of glucose in the blood (too much glucose is very toxic to the body). It allows your body to use glucose by allowing it to enter the cells (without insulin glucose would just float around in your body: secreted by the beta cells of the pancreas from the islets of langerhans. Deals with low blood sugar levels : a peptide hormone that causes the liver to turn glycogen into glucose does the opposite as insulin, also secreted by the pancreas. Liver: sensitive to insulin levels and stores and turns glycogen into glucose when the pancreas secretes glucagon.
