Q: Through what does urine enter the bladder? Read this paragraph and choose the correct option from the provided answers: Nephrons filter about cup of body fluid per minute. In a 24-hour period, nephrons filter 180 liters of fluid, and 1.5 liters of the fluid is released as urine. Urine enters the bladder through the ureters.
