Figure 6.16 shows the role of glucagon and insulin in the control of blood glu- cose levels. Convert each of these diagrams to a block control diagram, such as the one shown for blood pressure regulation in Box 6.3.

Include as much information from Section 6.4.2 as possible into your block diagram.
