What Is It?
The vas deferens is a long narrow tube that carries sperm from the epididymis to the seminal vesicles, where the sperm combines with fluids to make semen during ejaculation. People with penises have one vas deferens for each testicle.
An Example
Jamel understands that sperm and semen are not always together inside the body. The vas deferens moves sperm toward the urethra to mix with semen before ejaculation.
