  4. 4. 5  Referred to as the outer lips  They have a darker pigmentation  The Labia Majora FUNCTION:  Protect the introitus and urethral openings  Are covered with hair and sebaceous glands  Mass of fat, plexus of veins
  5. 5. 6 LABIA MINORA (Nymphae)  Referred to as the “inner lips”  Made up of erectile, connective tissue that darkens and swells during sexual arousal  Located inside the labia majora  They are more sensitive and responsive to touch than the labia majora
  6. 6. 7 CLITORIS  Highly sensitive organ composed of nerves, blood vessels, and erectile tissue  It is made up of a shaft and a glans  Becomes engorged with blood during sexual stimulation (2*1)  key to sexual pleasure for most women  Urethral opening is located directly below clitoris
  7. 7. 8 VAGINAL OPENING INTROITUS  In virginal women hidden by overlapping labia minora  Opening may be covered by a thin sheath called the hymen  Imperforated hymen:  vaginal orifice is occluded completely ,retention of menstrual discharge
  8. 8. 9 PERINEUM  The muscle and tissue located between the vaginal opening and anal canal  It supports and surrounds the lower parts of the urinary and digestive tracts  The perinium contains an abundance of nerve endings that make it sensitive to touch  An episiotomy is an incision of the perineum used during childbirth for widening the vaginal opening
  9. 9. 10 INTERNAL GENITALIA The internal genitalia consists of the:  Vagina  Cervix  Uterus  Fallopian Tubes  Ovaries
  10. 10. 11 Female Internal Reproductive System (side view)
  11. 11. 12 Female Internal Reproductive System (front view).
  12. 12. 13 VAGINA  The vagina connects the cervix to the external g enitals  It is located between the bladder and rectum  It functions :  As a passageway for the menstrual flow  For uterine secretions to pass down through the introitus  As the birth canal during labor  With the help of two Bartholin’s glands becomes lubricated during sexual intercourse
  13. 13. 14  The cervix connects the uterus to the vagina  The cervical opening to the vagina is small  This acts as a safety precaution against foreign bodies en tering the uterus  During childbirth, the cervix dilates to accommodate the passage of the fetus  This dilation is a sign that labor has begun
  14. 14. 15 UTERUS  A pear shaped organ  Located between bladder and rectum  Length: Nulliparous(6 to 8),Multiparous(9 to 1 0)  It is made up of the endometrium, myometriu m and perimetrium  The powerful muscles of the uterus expand to accommodate a growing fetus and push it thr ough the birth canal
  15. 15. 16  Length:8 to 14 cm  Serve as a pathway for the ovum to the uterus  Are the site of fertilization by the male sperm  Portions: Interstitial, isthmus, ampulla, infundibulum  Fertilized egg takes approximately 6 to 10 days to travel th rough the fallopian tube to implant in the uterine lining
  16. 16. 17  Almond-shaped organs, development and extrusion of ova, synthesis and secretion of steroid hormones  A woman is born with approximately 400,000 immature eggs called follicles  During a lifetime a woman release 400 to 500 fully matured eggs for f ertilization  The follicles in the ovaries produce the female sex hormones, progesterone and estrogen  These hormones prepare the uterus for implantation of the fertilized egg
  17. 17. 18  Uterine and ovarian art  Uterine art:  Internal iliac (Hypogastric) art  Ovarian art:  Direct branch of Aorta
  18. 18. 19  Uterine veins ; Internal iliac vein ; Common iliac vein  Right ovarian vein ;IVC  Left ovarian vein ;Left renal vein
