Vas deferens
The vas deferens (pl.: vasa deferentia), with the more modern name ductus deferens (pl.: ductūs deferentes), is part of the male reproductive system of many vertebrates. The ducts transport sperm from the epididymides to the ejaculatory ducts in anticipation of ejaculation. The vas deferens is a partially coiled tube which exits the abdominal cavity through the inguinal canal.
