Ovarian fossa

Where are the uterine tubes located
Upper border of broad ligament

What is the infindulum
Funnel shaped distal portion of uterine tube which is edged with fingers like extensions called fimbriae

No
Menstruation review
Uterine lining thickens in preparation for embryo
Ovary releases mature oocyte into peritoneal cavity
Swept into uterine tube by fimbriae and propelled into the uterus by cilia in the uterine tubes
Usually takes 3 days – fertilization usually occurs in this time period and location
If fertilization occurs, the zygote (fertilized ovum) will go on to implant in the uterine wall for subsequent development
If something blocks the way, the zygote will implant in the uterine tube and will result in an ectopic pregnancy. The uterine tube cannot accommodate the size and will rupture, causing life-threatening hemorrhage that requires immediate surgery to stop.
If fertilization does not occur, the uterus sheds its lining (menstruation) and the cycle starts over again
