Q

Duct of the Epididymis

A
  • duct behind the testis
  • sperm passes through this duct to the vas deferens.
  • 20 day journey for sperm to move through
  • During the journey, the sperm gains the ability to swim and fertilize

Q

Vas Deferens/ Ductus Deferens

A

From the duct of the epididymis the sperm travels to the vas deferens, then the ejaculatory duct, and to the urethra

Q

Duct System of the Male Reproductive System

A

Sperm is produced in the seminiferous tubules and travels in this order:
- Efferent ductules of the testes
- Duct of the epididymis
- Vas deferens
- Ejaculatory duct
- Urethra (prostatic, membranous, penile sections)

Q

Prostate Gland

A
  • Accessory gland of the male reproductive system
  • Encircles the prostatic urethra
  • Consists of 20-30 compound tubuloalveolar glands
  • Secretes about 25-30% of seminal fluid
  • Contains substances that enhance sperm motility
17
Q

Bulbourethral Glands

A
  • Accessory gland of the male reproductive system
  • Pea-sized glands inferior to the prostate gland
  • Produce a mucus that enters the spongy urethra prior to ejaculation
18
Q

What does the Muscous from the bulbourethral glands do?

A

cleanses urethra and enhances pH to enable fertilzations

19
Q

Ovaries

A
  • primary female sex organ (gonads)
  • produces ova/eggs (gametes)
20
Q

Uterine Tubes/ Fallopian Tubes

A
  • site of fertilization of the egg (fertilized egg turns to zygote and moves to the uterus
21

24
Q

Isthmus

A

25
Q

Uterus

A

Hollow muscular organ that prepares to support a developing embryo

26
Q

Regions of the Uterus

A

A

vulva

33
Q

Mammary Glands

A
  • Breasts
  • Modified sweat glands
  • the milk-producing gland
  • undeveloped in non-pregnant women
  • milk production starts after childbirth
34
Q

Regions of the Mammary Glands

A
  • Nipple
  • Areola
  • Lactiferous ducts
  • Lactiferous sinus
35
Q
