Leave a comment. Justin Timberlake may have been nominated at the Oscars on Sunday night, but if the 36-year-old was nervous he wasn't letting it show. Instead, the Mirrors hitmaker showed off his mischievous side after he and wife Jessica Biel had arrived for Hollywood's glitziest night and posed together for pictures.
Function of Ureter | Health Dictionary. Ureter, in a human organism, is a muscular tube, fairly thick and rigid, that leads URINE from the kidney to the urinary BLADDER. Both of the two tubular structures arise from the renal pelvis and collect the urine from the kidneyâs collecting tubules.
In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually 25â30 cm (10â12 in) long and ~3â4 mm in diameter.Histologically, the ureter contains transitional epithelium and an additional smooth muscle layer in the more distal one-third to assist with peristalsis.t the entrance to the bladder, the ureters are surrounded by valves known as ureterovesical valves, which prevent the backflow of urine. In females, the ureters pass through the mesometrium and under the uterine arteries on the way to the urinary bladder.
