the.com/ureter
a muscular straw that actively pumps your urine uphill, defying gravity twice daily and constantly.
means Either of the two narrow muscular tubes that carry urine from each kidney down to the bladder.
from From Greek 'ourētēr,' meaning 'a urinary canal,' built on 'ourein,' to urinate — itself rooted in 'ouron,' urine. The same root waters words like 'urine' and 'urea.' English borrowed it through anatomical Latin, and the careful clinician keeps it distinct from its near-twin 'urethra' (the single exit pipe below the bladder), which shares the same Greek family but a different job.
