DID YOU KNOW?

What happens to food in your body? When you

chew it in your mouth, it gets broken into pieces

and mixed with saliva (spit). Then you swallow

the food down, and it passes through the

esophagus (food pipe) into your stomach. The

stomach is a muscle that looks like a small bag.

This is where the stomach acid gets into the act,

and the food is churned until only a liquid pulp

remains. If you chewed well, there won’t be any

recognizable pieces left — which is great,

because that way your body can make much

better use of the nutrients. Then the food pulp

(called chyme) moves into the small intestine,

where it is broken down even more and the

nutrients are absorbed into the blood. The rest is

waste — whatever is left over goes into the large

intestine. There, water is pulled from the pulp,

which becomes more solid: This is where the stool

is formed. The stool leaves your body and gets

into the toilet through the anus, which is the exit hole in your bottom.

Every human has to eat, because the body gets energy from food. We need energy

to keep ourselves warm, to move, to think, and, of course, to grow.

WHAT’S HAPPENING

Everything that you eat moves through your body

and is used there. On the way, nutrients are retrieved

from foods, and what is left is the stool. You have probably noticed that

it doesn’t always look the same. Look at what’s in the toilet bowl!

Sometimes the color changes a little — depending on what you ate

before. A beet will turn your stool reddish, spinach will turn it grayish

green, and carrots turn it light brown to orange. And sometimes — if you

didn’t chew for very long — you can even see entire pieces of food in

there. That can happen with corn, sunflower seeds, or nuts, for example.
