Answer: The digestive system helps you swallow water (and food), and transports the waste to the urinary system.
Explanation:
I'm not sure what the respiratory system has to do with water (other than the body it's in, and water vapor). Sorry.
Water also helps with urea and getting rid of waste the more water you drink the less water the body will need to take from the amount you drank to get rid of the waste
If that makes any sense
