(mechanical engineering)
A fluid flow passage which may range from a few inches in diameter to many feet in rectangular cross section, usually constructed of galvanized steel, aluminum, or copper, through which air flows in a ventilation system or to a compressor, supercharger, or other equipment at speeds ranging to thousands of feet per minute.

In tetrapods, spermatozoa are released into the lumen of the seminiferous tubules and transported through the efferent ducts to the epididymis, from where they will be ejaculated into the female reproductive tract (Eddy, 2006).
Finally, control of the fluid composition of the lumen of the seminiferous tubules by Sertoli cells and by the efferent ducts and epididymis by epithelial cells is essential for the transport, maturation, and concentration of spermatozoa (Setchell et al.
