  1. Organs of the female reproductive organs
    • Produce and maintain the female sex cells
    • Transport the egg to the site of fertilization
    • Provide a favorable enviroment for the developing fetus
    • Produce female sex hormone
  2. Organs of the female reproductive system
    • Primary sex organs
    • Two ovaries
    • Internal acessorcy sex organs
    • Uterin tube,uterus, and vigina
    • External accessoru organs
    • Labia major labia minor clitoris and vestibular gland
  3. Ovaries
    • Devided into inner medulla and outer cortex
    • Medulla
    • Loose connective tissue that ccontain blood vessels lympatic vessel and nerves
    • Cortex
    • Contains the ovarian follicles
    • Before birth, they contain primordial folicles
    • Each follicle consists of a primary oocyte surrounding follicle cell
    • Primary oocytes starts cell division but does not finish until puberty
    • A million oocytes remain at birth
    • Only 400,000 are present at puberty
    • Only about 500 are released during female reproduction
  4. Oogenesis
    • Is the process of egg cell formation
    • Beginning at puberty primary oocyte continues cell divisionyeilding a secondary oocyte and a polar body
    • Secondary oocyte is the on that get fertilizex
  5. Maturation of the follicle
    • Due to hormonal release (FSH and LH) the primordial follicle mature into primary follicle
    • Primary oocyte enlarges and fills up with fluid
    • The secondary oocytes forms and is surrounded by zona pellicuda (glycoprotein) attached to corna radiata (follicular cells)
    • The secondary oocyte is released (ovulation)
  6. Uterine tubes
    • also called fallopian tubes or oviducts
    • Open near the ovaries
    • Fimbrae are fingerlike extensions that sweep the egg from the ovaries
    • Lined with ciliated columnar epithealium to move the fertilized egg toward the uterus
  7. Uterus
    • Hollow muscilar organ
    • Recieves the embryo and sustain its development
    • Upper two thirds is the body lower third is called the cervix
    • Has three layers
    • Endometerium
    • Myomertrium
    • Perimetrium
  8. Layers of the uterus
    • Endometrium
    • Covered twith columnar epithelial cells
    • Mymetrium
    • Smooth mucle
    • Perimetrium
    • Serosal layer
  9. Hormonal control
    • Estrogen and progesterone are released from the ovaries
    • The release of these hormones is controlled by the anterior pituitary glandhormones LH and FSH the amount of estrogen and progesterone surges at puberty and fluctuates during female menstral cycle
  10. Vagina
    • Fiberomuscular tube
    • Receives penis
    • Provide an open channel for child birth
    • Has three layers
    • Inner mucosal layer
    • Middle smooth muscle layer
    • Outer fiberous layer
  11. Function of estrogen
    • Enlargement of the accessory organs
    • Development of breasts
    • Increase deposits of adipose tissue in breasts thighs, and buttocks
    • Increases vascularization of the skin
  12. Function of progesterone
    • Promotes changes in the uterus during menstrual cycle
    • Affects the mammary glands
    • Helps regulate the release of FSH and LH from the anterior pituitary gland
