Final answer:
The statement that peristalsis occurs in the ureters to move urine from the kidneys to the urinary bladder is true. The ureters use peristaltic contractions to propel urine efficiently into the bladder.
Step-by-step explanation:
Peristalsis indeed occurs in the ureters to move urine from the kidneys to the urinary bladder. This statement is true. Peristalsis refers to the rapid, involuntary, wave-like contractions of the smooth muscles. Within the urinary system, these contractions help propel urine through the ureters without relying solely on gravity. The ureters, which are about 30 cm long, have walls composed of transitional epithelial lining and layers of longitudinal and circular smooth muscle that facilitate the movement of urine into the bladder. This process is an essential part of the body's excretion pathway, ensuring urine is efficiently transported from the kidneys to be stored temporarily in the urinary bladder before elimination.
