A) Ureters have sphincters at their entrances to prevent backflow of urine.
B) The ureters are lined with stratified squamous epithelium like the skin.
C) The ureters are capable of peristalsis.

Accepted Answer

The ureters are capable of peristalsis, which is the contraction of smooth muscles to propel urine from the kidney to the bladder. Choice A is incorrect as ureters do have a valve-like structure at their entrances to prevent backflow, but it is not a sphincter. Choice B is incorrect as the ureters are lined with transitional epithelium, not stratified squamous epithelium.
