内部性器官：生殖管道系统
|
位置、形状与功能
睾丸产生的精子由生殖管道运送直至从身体释放出去。这些成对的生殖管道（依次是：附睾、输精管和射精管）从睾丸引出，进入腹腔，最后与尿道汇合。尿道是一条既排出精子也导出尿液的单一管道。 |

The
Internal Sex Organs: The System of
Genital Ducts
|
Location, form and function
The sperm cells produced in the testicles are transported to their point of discharge from the body by a system of genital ducts. These ducts, which consist of matched pairs (in sequence: epididymides, vasa deferentia, ejaculatory ducts), lead from the testicles into the abdominal cavity where they eventually join the urethra, a single tube which discharges sperm as well as urine. |
