Question

where does the urinary tract begin? what is filtered in the urinary system? what percentage of the body is water? what is the function of the ureters?

Explanation:

The urinary tract begins at the kidneys. The urinary system filters waste products (such as urea, creatinine) and excess water from the blood. The human body is approximately 60% water (this can vary by age, gender, and body composition). The ureters are tubes that transport urine from the kidneys to the bladder.
