Verified step by step guidance

Understand the anatomy of the urinary system in both males and females. Both sexes have two kidneys, two ureters, a urinary bladder, and a urethra, so the number of kidneys and ureters is not a distinguishing factor.

Examine the structure of the urinary bladder. The urinary bladder is similar in both males and females, serving as a storage organ for urine before it is expelled through the urethra. Therefore, this is not the main difference.

Focus on the urethra, which is the tube that carries urine from the bladder to the outside of the body. In males, the urethra is significantly longer because it passes through the penis and also serves as a passage for semen during reproduction. In females, the urethra is shorter and located above the vaginal opening.

Recognize that the length of the urethra is the primary anatomical difference between the urinary systems of males and females. This difference has functional implications, such as females being more prone to urinary tract infections due to the shorter urethra.

Conclude that the correct answer is 'The length of the urethra,' as this is the main anatomical difference between the urinary systems of males and females.
