Overview of the Male Reproductive System
Here is a diagram of glucose homeostasis. When we eat food, our blood glucose concentration rises, which stimulates insulin secretion from β-cells and eventual glucose absorption by peripheral tissues. In between meals or in times of starvation, we are not taking in glucose and, therefore, experience a drop in blood glucose. During these times, the α-cells release glucagon, which stimulates the liver to make glucose by glycogenolysis and gluconeogenesis, and thereby raise blood glucose to normal levels.
