When you drink water, your body absorbs it like a sponge! Your sponge is made up of small tubes called blood vessels. These tubes are like straws that carry water all around your body. Your stomach and intestines also help to absorb the water by breaking it down into smaller pieces.
Then, the water is sent to your kidneys. Your kidneys are like special filters that clean your blood and remove waste. They also take out any extra water that your body doesn't need.
All of this happens without you even thinking about it! Isn't your body amazing?
