What are the female duct system called?
- Uterine tubes
- *fallopian tubes
Female duct system) Proximal to distal (4)
Female duct system) isthmus
Arises from the uterus
Female duct system) ampulla
This is common location for fertilization to occur
Female duct system) fimbria
fingerlike projection that move to catch the oocyte
Road to uterus) peristalsis
Helps propel the oocyte down
Road to uterus) dilated mucosa
Beating action of mucosal cells that line lumen to propel it down
Road to uterus) non-ciliated mucosa
Keep oocyte moist & nourished along the journey to womb
Uterus) 5 parts to it
Where uterine tube joins the body

Outer most layer of visceral peritoneum
Layers of uteran wall) myometrium
Thick smooth muscle layer
Layers of uteran wall) myometrium responsible for
Pushing the baby out
Layers of uteran wall) endometrium , 2 parts to it
Layers of uteran wall) endometrium, stratum functionalis (3)
Inner layer which undergoes changes with the menstrual cycle
Layer that gets shed during menstrual cycle
Closer to the lumen
Layers of uteran wall) endometrium, stratum basalis (3)
-placed more deeply, closer to the myometrium
-replaces functional layer after menstruation ends
