What tubes connect the kidneys to the bladder?

• A. Urethra
• B. Ureters
• C. Urethras
• D. Renal veins

Answer: (B)

The tubes that connect the kidneys to the bladder are known as ureters. Each kidney has a ureter that collects urine produced by the kidney and transports it to the bladder for storage before it is expelled from the body. The ureters have a muscular structure that helps move urine through peristaltic contractions, which are wave-like muscle movements. In contrast, the urethra is the tube that carries urine from the bladder out of the body, not connecting the kidneys to the bladder. Urethras is simply a variation of the term 'urethra' and does not refer to any additional structure; thus, it does not apply in this context. The renal veins are blood vessels that carry blood away from the kidneys to the heart, and they play no role in transporting urine.
