vas deferens : ウィキペディア英語版 | vas deferens
The vas deferens (Latin: "carrying-away vessel"; plural: vasa deferentia), also called ductus deferens (Latin: "carrying-away duct"; plural: ductus deferentes), is part of the male reproductive system of many vertebrates; these vasa transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. ==Structure== There are two ducts, connecting the left and right epididymis to the ejaculatory ducts in order to move sperm. Each tube is about long (in humans), 3 to 5 mm in diameter and is muscular (surrounded by smooth muscle). Its epithelium is lined by stereocilia. They are part of the spermatic cords. 〔Dr C Sharath Kumar, Ph D Thesis, University of Mysore, 2013〕
