Which statement about the ureters is true?

Which statement about the ureters is true?

• A. They are the site of filtration
• B. They are 10-12 inches long, muscular tube that extends from kidney to the bladder, lined by mucous membrane
• C. They produce ADH
• D. They are the primary site of reabsorption

Answer: (B)

The ureters are the tall, muscular tubes that transport urine from the kidneys to the bladder using rhythmic waves of peristalsis. They are about 25–30 cm (10–12 inches) long in adults and have a mucous membrane lining to protect the tissue from urine. This combination—lengthy muscular transport tubes with a protective mucosal lining—fits the described statement exactly. Filtration happens in the kidneys, not in the ureters; ADH is produced by the hypothalamus/pituitary and acts on the kidneys to regulate water reabsorption; and most reabsorption occurs in the kidneys, not in the ureters.
