vas
n. countablen. a small tube or vessel in the body that carries fluids, especially one that carries sperm. It is a technical term used in biology and medicine.
n. a vessel or duct that conveys bodily fluids, most commonly referring to the ductus deferens in the male reproductive system. Often appears in the plural form 'vasa'.
The surgeon carefully identified the vas during the procedure.
A vasectomy involves cutting and sealing the vas deferens to prevent sperm from entering the urethra.
In anatomical studies, the vas deferens is distinguished from other ducts by its thick muscular walls, which facilitate the rapid transport of sperm during ejaculation.
The plural form is 'vasa'. In medical contexts, it is almost always followed by a specific descriptor like 'deferens' or 'afferens'.
