Answer 1

The body still has to get the waste products out of the system. The stuff filtered out by the kidneys needs to get out of the body somehow and it can’t just sit in the bladder forever.

When you get dehydrated _enough_ urination does stop, but until that point expelling toxic (to the body) waste is a very high priority.
