We've now learn how food goes up the ascending colon on the right side of your body, across your transverse colon and down your descending colon.
After that the intestine curves back toward the middle of your body.
When it does this it makes a little curve upward.
This curve upward allows the body to get rid of gases without having to push out feces.
Feces is a fancy science word for poop, and we know passing gas means a toot!
These are all funny things we laugh about sometimes, but they are part of our bodies, and doctors have to know how they work so they can take care of us if we get sick.
So the curve up of the sigmoid colon lets us push gases out of our body without feces coming out too.
