The female reproductive system10 The female reproductive system10 Presentation Transcript

  • The Female Reproductive System (Part 1) oPlays a major function to ensure the continuation of the human species.oThe Reproductive System produces ova (the female reproductivecell)oProvides a place for fertilization to occur and for a baby to growduring pregnancy.oThe Breasts provide nourishment for the newborn.
  •  The Female Reproductive System consists of both internal and external genitals, the reproductive organs. Internal Genitalia are located in the pelvic cavity and consists of the uterus, two ovaries, two fallopian tubes, and the vagina.
  •  A hollow pear-shaped organ that contains a thick muscular wall, a mucus membrane lining and a rich supply of blood. It lies to the center of the pelvic cavity between the bladder and the rectum. It is normally bent slightly forward (anteflexion)  The uterus has three sections: the fundus (upper portion between where the fallopian tubes connect to the uterus. Corpus (the body) central portion and cervix or lower portion (the neck of the uterus), which opens into the vagina. The inner layer (endometrium) of the uterine wall contains a rich blood supply. It reacts to hormonal changes every month that prepares it to receive a fertilized ovum. It provides a place of nourishment and protection for the developing baby. If there is no fertilization, the endometrium is sloughed off, resulting in menstruation (shedding of the lining of the uterus)
  • Two Ovaries Small almond shaped glands that produce ova (ovum) and the female sex hormones. One located on each side of the uterus. Hormones from the anterior pituitary, follicle stimulating hormone and luteinizing hormones stimulate maturation of ovum and trigger ovulation ( the process by which one ovary releases an ovum The female sex hormones produced by the ovaries estrogen and progesterone stimulate the lining of the uterus to be prepared to receive a fertilized ovum.
  •  Uterine tubes or oviducts. 5 ½ inches long and run from the area around each ovary to either side of the upper portion of the uterus. The unattached ends of these tubes expand into fingerlike projections called frimbriae. The frimbriae catches an ovum after ovulation and directs it into the fallopian tube. The tube then propels the ovum from the ovary to the uterus so it can implant.
  • The Vagina Muscular tube lines with mucous membrane that extends from the cervix of the uterus to the outside of the body. Allows the passage of the menstrual flow. During intercourse, it receives the male penis and semen (fluid containing sperm) Serves as birth canal through which the body passes during a normal vaginal birth.
  •  What purposes does the vagina have in the female reproductive system? Where does fertilization take place? How many arteries are in the female reproductive system? What reproductive part protects a developing child?Review
