Insulin and glucagon are hormones that help regulate the body’s glucose levels.When the body digests food rich in carbohydrates, glucose is released into the bloodstream. This leads to an increase in blood glucose levels in the body. Consequently, the pancreas sends signals that direct all the cells in the body to take in the glucose. Most of this glucose is used up to provide energy to the cells. The excess glucose in the bloodstream is converted into glycogen and absorbed by the liver and muscle cells to be used later.
