The document summarizes the key structures and functions of the female reproductive system. It describes the external structures including the vulva, clitoris, and labia. It then details the internal structures such as the vagina, uterus, fallopian tubes, and ovaries. It explains the roles of these structures in reproduction, including gamete transport, embryonic development, menstruation, pregnancy, and childbirth.
Femalereproductivesystem
- 2. Introduction
- 3. External Female Structures Collectively, the external female reproductive organs are called the Vulva. Mons Pubis. Labia Majora Labia Minora. Clitoris. Vestibule. Perineum
- 5. Internal Female Structures Vagina Uterus Fallopian tubes Ovaries
- 6. Fallopian tubes The two tubes extended from the cornu of the uterus to the ovary. Length 8 to 14 cm average 10 cm Its divided into 4 parts.
- 7. Functions Gamete transport (ovum pickup, ovum transport, sperm transport). Final maturation of gamete post ovulate oocyte maturation, sperm capicitation. Fluid environment for early embryonic development. Transport of fertilized and unfertilized ovum to the uterus.
- 8. Ovaries Oval solid structure, 1.5 cm in thickness, 2.5 cm in width and 3.5 cm in length respectively. Each weights about 4–8 gm. Ovary is located on each side of the uterus, below and behind the uterine tubes
- 9. Structure of the ovaries Cortex Medulla Hilum Function of the ovary Secrete estrogen & progesterone. Production of ova
- 10. Uterus The uterus is a hollow, pear shaped muscular organ. The uterus measures about 7.5 X 5 X 2.5 cm and weight about 50 – 60 gm. Its normal position is anteverted (rotated forward and slightly antiflexed (flexed forward) The uterus divided into three parts
- 11. Parts of Uterus
- 12. Layers of the uterus Perimetrium. Myometrium. Endometrium.
- 13. Endometrium Is the inner layer of the uterus. It is responsive to the cyclic variations of estrogen and progesterone during the female reproductive cycle every month.
- 14. The Function of the uterus Menstruation ----the uterus sloughs off the endometrium. Pregnancy ---the uterus support fetus and allows the fetus to grow. Labor and birth---the uterine muscles contract and the cervix dilates during labor to expel the fetus
- 15. Vagina It is an elastic fibro-muscular tube and membranous tissue about 8 to 10 cm long. Lying between the bladder anteriorly and the rectum posteriorly. The reaction of the vagina is acidic, the pH is 4.5 that protects the vagina against infection.
- 16. Functions of the vagina To allow discharge of the menstrual flow. As the female organs of coitus. To allow passage of the fetus from the uterus. Bony Pelvis Is Composed of 4 bones: 1. Two hip bones. 2. Sacrum. 3. Coccyx.
