What is the name of the area that collects urine from the kidneys?

The renal pelvis is the correct answer because it is the anatomical structure within the kidney that serves as the funnel for urine flowing from the kidney into the ureter. After urine is produced in the nephrons, which are the functional units of the kidney, it drains into the renal pelvis. The renal pelvis then channels the urine into the ureter, which transports it to the bladder for storage until it is excreted.

Understanding the functions of the other options helps clarify why the renal pelvis is the correct choice. The bladder is the organ that stores urine until it is ready to be expelled from the body. The nephron, while critical in the formation of urine, represents the filtering unit within each kidney rather than a collecting area. The ureter acts as a duct that carries urine from the renal pelvis to the bladder, but it does not collect urine itself. Therefore, the renal pelvis is the key structure that plays the role of collecting urine from the kidneys.
