Let's Learn A Little Anatomy

This week, we're reading Gulp by Mary Roach.  And while we do want you to go read the book and learn all about the digestive system, I'm thinking just a little bit of background might be for the best in this case.

Do you remember that song about the bones you learned as a kid?  You know, "the toe bones connected to the foot bone."  No?  Well, here's a little reminder.

The digestive systems is kind of the same way.  Your mouth is connected to your throat, which is connected to your stomach, on to your small intestines, large intestines, down to the colon where it all comes out.

Now, of course, it gets a lot more complicated.  There are nutrients being pulled out along the way so that your body can power itself and the food is being broken down so that you can push it out the other side.  You also have tons of taste buds so that you put something in your mouth to begin with.  If food was nasty, we wouldn't really want to nourish ourselves.

So why is our digestive system to important that Roach felt the need to write a whole book on it?  Well, we started out as the digestive system.  We started eating and wasting before we started walking and talking as a species.  Evolution decided that if we were going to be eating, we should have a way to go find that food.

So brush up a bit on your digestive system before diving into our book this week.
