    Okay. It took me a long while to understand this graph. Do you understand it?

    Take a look at the bottom of the graph. It shows us three different things that we can find, in our small intestine. Hydrochloric acid, Proteins, and Fats.

    When our small intestine finds any of these things inside of it, it causes our pancreas to make "pancreatic juice."

    And this pancreatic juice can have different things in it, depending on what was inside the small intestine.

    Should I rephrase? Is there something you don't understand?

    Again, the kind of juice that the pancreas makes....depends on what is inside the small intestine.

    For example, if there is hydrochloric acid inside the intestine..... the pancreatic juice will have a lot of sodium bicarbonate. Take a look at the bar graph again. Do you see that?

    Okay. We need to understand the chemistry behind it. When sodium bicarbonate combines with hydrochloric acid..... it makes three things: 1. Salt 2. Carbon dioxide 3. Water

    So, again, if there is Hydrochloric acid inside of our small intestine, then our pancreas will make juice, with a lot of bicarbonate it.

    This is because we need sodium bicarbonate, in order to react with the Hydrochloric acid, and turn it into three things: 1. Salt 2. Carbon dioxide 3. Water In other words, we need sodium bicarbonate, in order to kind of break down the hydrochloric acid.

    So, can you look at the graph and tell me.. when there are fats inside of our small intestine, what kind of juice will our pancreas make? What will there be a large amount of, in the juice?

    Yes. Great. Here's what it means. If there are fats in our small intestine.... then there will be a lot of digestive enzymes, in our pancreatic juice. You get it?

    Here's a question: What if there's Hydrochloric acid in our small intestine? What will there be a lot of, in our pancreatic juice?

    And how about proteins? What if there are proteins in our small intestine? What will our pancreatic juice look like?

    RIght. There will be an equal amount of both.

    Alright. So let's go back to Fats. Again, when there are fats in our small intestine, our pancreatic juice will have lots of Digestive Enzymes in it. (We can see this on the graph.) This is because digestive enzymes are needed, in order to break down fat.

    And again, if we have Hydrochloric acid in our small intestine, then our pancreatic juice will have a lot of Bicarbonate in it. Because Bicarbonate is needed, in order to react and break down Hydrochloric acid.

    Our pancreas produces whatever is needed, in order to break down the things inside of our small intestine.

    It's a little blurry, but I'm pretty sure the first one is pointed at the fat cells. The second one is actually pointed at the "alveoli."

    Fat stores energy away for us. Our body uses the energy, whenever it needs it, in order to stay alive. Fat also keeps us warm.

    Yeah. It's our body's way of keeping a steady internal environment.

    No problem. Don't forget to mention the part about how our body stores fat, for energy.
