Muscular duct that propels urine from the kidneys to the urinary bladder, or related organs.
Comment:
[homology-note] "The first embryonic hint of a metanephros is the formation of the metanephric duct that appears as a ureteric diverticulum arising at the base of preexisting mesonephric duct. The ureteric diverticulum grows dorsally into the posterior region of the nephric ridge. Here it enlarges and stimulates the growth of metanephric tubules that come to make up the metanephric kidney. The metanephros becomes the adult kidney of amniotes, and the metanephric duct is usually called the ureter.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000605", ontology="VHOG", source="ISBN:978-0072528305 Kardong KV, Vertebrates: Comparative Anatomy, Function, Evolution (2006) p.543", source="http://bgee.unil.ch/"}; [structure-note] "in humans, consists of adventitial, muscular and mucoa layers"
