Reproductive System Function

Perpetuate the Species

What are the function of the gonads, the testes, and the ovaries?

Produce Germ Cells

Female Uterus Function

Provides a nurturing, protective environment in which the embryo (later called the fetus) develops until birth

What is the EXOCRINE and ENDOCRINE function of the testes?

Testes = male gonads

Exocrine Function: Sperm Reproduction
Endocrine Function: Testosterone Production

Epididymis Function

Provides a site for immature sperm entering it from the testis to complete their maturation process.

What is ejaculation?

Contraction of the ejaculatory duct propels the sperm through the prostate to the prostatic urethra (which in turn empties out into the membranous urethra, and then the penile urethra)

What do to the prostate, seminal vesicles, and the bulbourethral glands produce?
& what is the products function?

Seminal Fluid - liquid medium in which sperm leaves the body

Prostate Function

Secretes a milky fluid into the urethra
(which plays a role in activating sperm)

Bulbourethral Glands Function

Produce a thick, clear, alkaline mucus that drains into the membranous urethra

Penis Function

Deliver sperm into the female reproductive tract

Seminiferous tubules Function

Sperm Forming Factories

Stereocilia (in Epididymis) Function

Absorb excess fluid and pass nutrients to the sperm in the lumen

What is the EXOCRINE & ENDOCRINE function of the ovaries?

Ovaries = Female Gonads

Exocrine Function = Produce Eggs (Ova)
Endocrine Function = Produce Estrogens and Progesterone

Hymen Function

Lubricate the distal end of the vagina during coitus

Vagina Function

Serves as a copulatory organ and birth canal and permits passage of the menstrual flow

Functional Layer (of Endometrium) Function

Sloughs off in response to cyclic changes in the levels of ovarian hormones in the woman's blood (about every 28 days)

--> known as Menstruation

Basal Layer (of Endometrium) Function

Forms a new functional layer after menstruation

Broad Ligament Function

Fold that encloses the uterine tubes and uterus and secures them to the lateral body walls

Round Ligament Function

Help attach the uterus to the body wall

Ovarian Ligament

Supports the Ovaries Medially

Suspensory Ligaments

Support the Ovaries Laterally
