Definition of ureter in English:



Zoology Anatomy
  • The duct by which urine passes from the kidney to the bladder or cloaca.

    • ‘The urine is passed to the bladder through ureters from each kidney in peristaltic waves.’
    • ‘One of the more common congenital abnormalities (meaning abnormalities that exist at birth) is duplication of the ureters, in which a kidney has two ureters coming from it instead of one.’
    • ‘Irritation of the lining of the kidney, the ureter or bladder can lead to the presence of blood in the urine.’
    • ‘No changes were found in the renal pelvis, ureter, and urinary bladder samples.’
    • ‘Your urinary system is composed of your kidneys, ureters, bladder and urethra.’
    • ‘Smoking is also associated with cancers of the mouth, pharynx, larynx, esophagus, stomach, pancreas, cervix, kidney, ureter, and bladder.’
    • ‘Peristaltic activity, influenced by urine volume, propels urine along the ureter into the bladder.’
    • ‘The kidneys and urinary tract (which includes the ureters, bladder, urethra, and the kidneys) filter and eliminate these waste substances from our blood.’
    • ‘They occur when the kidneys, ureters, bladder, or urethra become infected.’
    • ‘Usually the stones are small enough and pass through the ureter to the bladder and out in one's urine. Stones that are too large to pass can cause kidney failure.’


Late 16th century: from French uretère or modern Latin ureter, from Greek ourētēr, from ourein ‘urinate’.
