Flexi Says: The amount of water lost in urine is controlled by the kidneys, the main organs of the excretory system along with endocrine glands. When you have excess intake of fluids then you would go frequent urination that would be diluted and higher volume than usual. Unlike a low level of water in the blood triggers retention of water by the kidneys. The kidneys produce more concentrated urine, so less water is lost from the body.
