Okay, kiddo, have you ever heard of an artificial bladder before? It's a special kind of bag that doctors can put inside someone's body when they can't pee on their own.
You see, our bodies have these organs called bladders that store the pee our kidneys make until it's time to go to the bathroom. But sometimes people get sick and their bladders stop working. This can be really uncomfortable and make it hard for them to do things they love, like playing outside or spending time with their friends.
So doctors came up with a solution! They made these little bags out of special materials that won't harm the body. When someone needs one, the doctor puts it inside the body and attaches it to their pee tubes. Then, when the person needs to pee, the bag fills up just like a normal bladder would.
It might not sound like a lot, but having an artificial bladder is actually a really big deal! It can help people who are sick feel more comfortable and have a better quality of life. Plus, it's a really cool invention that we should be thankful for!
