Why do we pee and do we have to do it

Answer and Explanation:

We pee because our body needs a way to get rid of the excess waste and water in our system. And, yes, we do need to pee. It's as natural as breathing. So, when we drink, what do we do? We pee. Simple.

When you feel the urge to pee and have to sprint to the bathroom in case you can't make it by walking, the brain signals the bladder muscles to tighten, squeezing urine out of the bladder. At the same time, though, the brain signals the sphincter muscles to relax, and so, as these muscles relax, urine exits the bladder through the urethra. When all the signals happen in the correct order, normal urination, or peeing, occurs.
