Final answer:
The Ductus epididymis is a tubule in the male reproductive system responsible for receiving, maturing, and storing sperm.
Step-by-step explanation:
The Ductus epididymis is a tightly coiled tubule located in the male reproductive system. It is made up of smooth muscle, connective tissue, and a ciliated epithelium lining. The Ductus epididymis is responsible for receiving sperm from the seminiferous tubules in the testis, maturing the sperm, and storing it until ejaculation.
