Reproduction System

Reproductive System

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.
