Explanation The internal structure of testis includes: Tunica albuginea: This is white fibrous tissue and is responsible for dividing the testis into compartments known as lobules. Seminiferous tubules: Each lobule consists of one to three highly coiled seminiferous tubules. This is the place where sperm is made. Mediastinum has its role in supporting blood vessels and the lymphatic system of the testis. It also encloses the rete testis inside the testis. Straight tubules: This connects the two seminiferous tubules and the rete testis. Rete testis refers to the channel in which the seminiferous tubules open and it also facilitates the movement of the sperm via the testes and carries them to the duct of the penis. Efferent ducts refers to the connection present in the rete testis and epididymis. It is responsible for facilitating the transport of the sperm. Ductus deferens is the muscular duct that is responsible for the transport of spermatozoa via the epididymis to the ejaculatory duct. Ejaculatory duct is the merging point of the seminal vesicle with vas deferens. The internal structure of the testis is shown below: Production of the sperm cells: The production of a sperm cell is known as spermatogenesis and it takes place inside the seminiferous tubules present within the testes...
