From the brains behind brains on, this is the moment of um.

Moment of um.

Moment of um comes to you from APM Studios. I'm Barry, and I'm a speck of black pepper.

I have the best job in the entire world, seasoning your food.

My buddies and I live inside a pepper shaker on your kitchen table, waiting for the day that you decide to sprinkle us on a delicious meal.

Lots of nights, when the rest of my pepper buds are snoozen, I lay awake and imagine what kind of food I'll get to season someday.

Spicy Kimchi ramen, scrambled eggs,

Caesar salad, the possibilities are endless. But sometimes I get a little impatient. Like I can

hear your Tommy rumbling from across the room and I think come on just grab a meal and sprinkle me on it

I know you're hungry I mean I think a rumbly tummy means you're hungry, right?

Huh, why does it do that anyway?

Rosemary was just asking about this.

Hi, my name is Rosemary, and I'm from Dallas, Texas. My question is, why does your stomach

rumble when you're hungry? Hi, I'm Lily Dara. I am a gastrantroologist and an assistant professor of medicine at the University of Southern California in Los Angeles. and bowel and liver and pancreous disorders. So basically if you have a tummy ache or if you have

diarrhea or liver disease and you'd come to a gastronautologist. So to start off you have to understand what the GI system, the stomach and the intestines do.

Basically their job is to get all the good stuff out of food, what we call nutrients,

so that we can grow stronger and we can remain healthy.

In order to do that once you eat the food, the stomach and the intestines have to move around

and squeeze the food and turn it into smaller pieces.

Imagine you're holding a cracker in the palm of your hand, and when you make a fist,

you squeeze your hand muscles to break that cracker into pieces.

The stomach is basically like a balloon made up of muscles, and that's what it does.
