Which of the following statements is true regarding the urinary tubule in the excretory system?

The urinary tubule is a long, winding tube in the kidney nephron where urine is made. After blood is filtered in the glomerulus, the liquid passes through the tubule. The tubule removes waste and extra water to create urine.

Blood filtration happens in the glomerulus, not the tubule itself. The ureter connects kidneys to the bladder, not the urinary tubule. The tubule does help regulate water and electrolytes, but this is part of how it produces urine, not a separate function.

As liquid flows through the tubule, useful substances like glucose and some water are absorbed back into blood. Wastes like urea and extra salts stay in the tubule and become urine. The final urine then flows to the bladder for storage.
