Why is urine called urine? why is the urinary system so important ?

The urinary system allows your body to successfully filter out your blood, creates urine as a waste product, then stores and excretes it. But that's not all it does. The urinary tract system is an integral part of your body's overall maintenance as it works to maintain homeostasis and produce necessary hormones. The English word urine (/ˈjuːrɪn/, /ˈjɜːrɪn/) comes from the Latin urina (-ae, f.), which is cognate with ancient words in various Indo-European languages that concern water, liquid, diving, rain, and urination.
