Which structure connects the kidneys to the urinary bladder?
Ureter
The human excretory system consists of a pair of kidneys, two ureters, a urinary bladder and a urethra, each with a specific role in forming and removing urine.
The ureters are long, narrow muscular tubes that arise from the inner side of each kidney and carry the urine formed there downwards into the urinary bladder, where it is stored until it is passed out of the body.
The urethra, in contrast, is the tube that carries urine from the bladder to the exterior, while the renal pelvis is only the funnel-shaped region inside the kidney.
Hence, the correct answer is Ureter.
