Sew a seam 7 inches from the folded edge to make a tube. Stitch twill tape in place. Thread elastic through the towel's existing hem: Snip one small slit in the towel's hem. Flip tube over and repeat, making a second slit. Tie a large knot at one end of elastic; attach safety pin to other end. Slide safety pin through 1 slit, and ease through hem and out other slit. Tie elastic ends to gather.
Glucagon causes the liver to release stores of glucose from hepatic polymers called glycogen, it also signals the liver to start a process called gluconeogenesis, in which glucose is produced from amino-acids after hepatic glycogen stores are depleted.
Glucagon works along with the hormone insulin to control blood sugar levels and keep them within set levels. Glucagon is released to stop blood sugar levels dropping too low, while insulin is released to stop blood sugar levels rising too high. Release of glucagon is stimulated by low blood glucose (hypoglycaemia), protein-rich meals and adrenaline (another important hormone for combating low glucose). Release of glucagon is prevented by raised blood glucose and carbohydrate in meals, detected by cells in the pancreas.
