why do stomachs make noises when were hungry?
In: Biology
A cool way to experiment with what’s happening in your stomach when you’re hungry is to get a garden hose. Since it has two ends that can be opened or closed, it’s sort of like your digestive system: a continuous tube that starts at your mouth and ends at your butt.
If the hose is empty, there’s no sound. Your digestive system is basically never totally empty, but if it were it, too, would be quiet.
Put some water in the hose, but don’t seal it on either end. Move the ends around and you’ll hear the air and water fighting. That’s basically what happens in your guts when there is room for stuff to slosh around.
What you’re really hearing is air and fluids negotiating positions. When the air gets closer to the bottom of your inner hose, guess what happens?
Come on, guess.
