DUCT SYSTEM

• Uterine (fallopian) tube structure

  • Infundibulum - distal, funnel-shaped end
  • Fimbriae - fingerlike projections of the infundibulum that receive the oocyte from the ovary
• Uterine (fallopian) tubes - initial part of the duct system; receives the ovulated oocyte from the ovaries
• Uterus - situated between the urinary bladder and rectum; receives a fertilized egg; size and shape of a pear in a woman who has never been pregnant
• Uterine support:

  • Broad ligament - suspends the uterus in the pelvis
  • Round ligament - anchors the uterus anteriorly
  • Uterosacral ligament - anchors the uterus posteriorly
• Regions of the uterus:

  • Body - main portion
  • Fundus - superior rounded region above where uterine tube enters
  • Cervix - narrow outlet that protrudes into the vagina
• Layers of the uterus (superficial to deep):

  • Perimetrium
  • Myometrium
  • Endometrium
• Vagina - extends from cervix to exterior of body; allows a baby or menstrual flow to leave the body
• Hymen - partially closes the vagina until it is ruptured
