Top Text Title: Top Text: Vulva - Comprised of the female external reproductive organs. A.) External Reproductive organs: Purpose - Protection from trauma and pathogens 1.) Mons pubis - Fatty tissue, pubic hair, on the top of the pubic bone. 2.) Labia's - Purpose: protection from pathogens, cover clitoris. Labia Majora - Outer folds that protect the reproductive system Labia Minor - Inner folds that protect the reproductive system 3.) Clitoris - This organs important function is producing sexual arousal, (nerve endings and blood vessels). 4.) Bartholins Glands - Secretion of fluid during sexual arousal. 5.) Vaginal opening - Opening to the vagina 6.) Urethra opening - Passage way for urine. B.) Internal Reproductive organs: 1.) Vagina - This is called the Birth canal. Female organ of intercourse. Elastic, tubelike passageway, approximately four to five inches long. 2.) Hymen - Membrane inside the vagina opening, protects from pathogens 3.) Cervix - This is the neck of the uterus, purpose: dialation. 4.) Uterus - Holds and nourishes the developing embryo, fetus and child. Elastic muscle It is the size of a fist. 5.) Endometrium The lining of the uterus, rich blood vessels. 6.) Fallopian Tubes - Fertilization of the ovum usually occurs in the widest part of the tube. 7.) Fimbriae Fibers - Finger like projections at the end of the fallopian tubes, sourround the top of the ovaries. Celia in the fimbria gather a released ovum into the Fallopian tube. 8.) Ovaries � Produce the female hormones estrogen and progesterone. At birth a female has 200,000 to 300,000 immature ova in her ovaries. Ovum / ova - The female reproductive system functions to produce mature ovum. Abdominal cramps - This feeling occurs when the uterus contracts to breakdown the endometrium. Bladder - Mushroom shaped organ of the urology system. The Menstrual Cycle 1st half cycle - (1-14 days) Pituitary hormone (Follicle Stimulating Hormone) Stimulates egg to mature inside the ovary. Rebuilds endometrium Ovulation - Each month one ovary releases one mature ovum into the fallopian tube. (5-7 days) ( Lutein Hormone released) Menstruation - If the ovum is not fertilized, uterine lining is not needed. The muscles of the uterus contract. The lining (endometrium) breaks down, passes through the vagina and out the body. (5-7 days) (estrogen increases, thickens lining of uterus) Fertilization - When the sperm enters the mature ovum. Continuum of life : Marture egg - Fertilized egg - Zygote - Blastocyst - Embryo - Fetus - Child - Adolescent and Adult. Endocrine System - Pituitary gland (growth/metabolism/reproduction) Identical: Same fertilized egg (zygote) Faternal: 2 eggs are released from ovary, 2 sperm 46 Chromosomes - Male XY - Female XX - determination of child based on fathers sperm.
