Complete each of the following statements by dragging the word or phrase into the proper position. Then rearrange the statements into the correct order of appearance in the male duct system starting with the creation of sperm.

1- The secretions of the male reproductive tract ___originate____ in the testes where ___sperm___ are produced. 2- The fluid from the __seminal vesicles____ joins sperm from the __ductus deferens___ at the ejaculatory duct. 3- The second largest producer of seminal volume, the __prostate gland__ surrounds the urethra and ejaculatory duct. 4- Contributing a small portion of the overall seminal volume (5%), the ___bulbourethral glands___ are involved with preejaculatory secretions for lubrication and preparation of the urethra for the passage of sperm.

Paired glands that secrete into urethra

Bulbourethral glands

Located within spermatic cord

Ductus deferens

Process by which semen is forced out through urethra

Ejaculation

Stores immature sperm

Epididymis

Contains three columns of erectile tissue

Penis

Often removed in circumcision

Prepuce

Surrounds the urethra and secretes a milky fluid

Prostate

Contains sperm and secretions from accessory glands

Semen

Location of spermatogenesis

Seminiferous tubules

Process by which sperm are formed

Spermatogenesis

True

Produce male hormones

Interstitial cells

A spermatogonium divides

by mitosis to produce a spermatogonium and a primary spermatocyte.
