Label the major structures of the male reproductive system in this sagittal view

1- ductus deferens
These ducts transport sperm from the epididymis to the ejaculatory ducts in the seminal vesicle in anticipation of ejaculation.

2- urethra
 Urethra is connected to the bladder for the removal of urine from the body. It's also a part of the male reproductive system because let's the semen out of the body.

3-penis
the organ that delivers the sperm during copulation. It's composed by a shaft and the glans penis.
4- glans penis It's the enlarged bulbous-shaped tip in the penis.

5-prepuce It's a layer of muscle,mucous membrane and skin tissue (plus blood vessels, neurons) that covers and protects the tip of the penis.

6-testis
is the male reproductive gland that produces the sperm and androgens, primarily testosterone. It's protected by the scrotum.

7-scrotum It's a structure that looks like a pouch. It's behind the penis and holds and protects the testicles.

8-seminal vesicleProduces a alkaline fluid, composing 70% or more of the semen that helps reduce the acidity of the vaginal tract, that way, the sperm won't die. It also contains nutrients to keep them alive for longer.

9-prostate
Produces a alkaline liquid, composing part of the semen that helps reduce the acidity of the vaginal tract, that way, the sperm won't die.

10-  bulbourethral glands
Also called Cowper's glands, they are located posteriorly and laterally to (the membranous portion) the urethra, at the base of the penis. Its function is to produce a liquid that cleans the urethra from urine that remains. That way, the sperm won't die.

11-epididymisThe epididymis is composed by coiled tubes against the testicles and its function is mature and store the sperm.
