Keep a couple of things in mind when you’re looking at Figure 4.10. First, the human body strives to maintain balance – whether we’re talking about maintaining body temperature or acidity, or in this case, regulating blood glucose levels to keep them fairly stable. If you think about it, whether you eat every couple of hours or haven’t eaten all day, it’s likely that your blood sugar will not stray too far above or below the normal range, as shown to the right of the figure. This illustration explains how the body accomplishes that task and prevents excessive drops or elevations in blood glucose. Although opposing mechanisms are involved in lowering and raising blood sugar, understanding what happens in one direction will make it easier to understand the opposite one. Just remember – high blood sugar promotes storage while low blood sugar favors the release of stores. Here, the top of the figure shows what happens to blood sugar just after you eat. The bottom shows what happens when you haven’t eaten for a few hours.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
