Science

• Reproductive System


  Important to produce offspring
• Male Reproductive System 


  Produce and transport sperm cell
• Female Reproductive System


  Receive sperm, produce egg cell, child bearing
• Without the fashion of the sperm cell and egg cell, reproduction will not occur
• Urethra


  Tube that passes through the penis and carries urine and sperm
• Epididymis

  • Coiled j shaped tube located at the back of each testicle.
  • Stores the sperm for 2 to 4 days after have been produced
• Penis

  • External sexual organ of male
  • Contains erectile tissue in wich penis became larger and stiffer dur to increase flow of blood during ejaculation
• Vas deferens

  Tube that receive sperm form the epididymis
• Testes

  •Coiled tubules wich the sperm are produce

  • Produce testosterone for the production of sperm
• Testosterone

  Male sex hormone
• Scrotum

  • Pouch of skin that hangs from the penis
  • Protects the sperm
• Vas deferens

  Time that's is 18 inches and loops over urinary bladder
• Urethra

  • Common tube where urine and semen passes
  • The valve within the urethra prevents the mixing of urine and sperm
• Seminal vesicles 


  At the base of the urinary bladder that secrete fluid that Nourish the sperm
• Ejaculated ducts

  • Tubes that are lined with muscles
  • This muscles contract to force the semen out of the body during ejaculation
• Sperm cell

  • Unique structure located in the testes
  • Primary function is to fertilize the egg
• PARTS OF MALE REPRODUCTIVE SYSTEM

  1. Urethra
  2. Epididymis
  3. Penis
  4. Scrotum
  5. Vas deferens
  6. Testes
• Ovaries

  • Small and almond shaped organ
  • Secrete hormones called progesterone and estrogen
• Puberty

  • Egg cells begin to mature
  • Stage when child's body start to develop
• Ovulation 


  During puberty, ovaries produce and release one ripened egg every 28 days
• Fallopian /Uterine Tubes

  • 2 tubes that extend from each ovary into the uterus
  • House the egg until fertilization
  • Provides passageway leading the sperm to the egg and the fertilized egg to the uterus
• Uterus or womb

  • Hollow muscular pear shaped organ located between the two ovaries
  • Fertilize egg will develop and grow into offspring
• Cervix 


  Narrow structure within an inch long canal
• Vagina or birth canal

  • Hollow tube leading from the cervix to the outside of the body
  • Wall is elastic wich allows it to expand during childbirth and sexual intercourse
• Vulva

  External genitalia
• Mons veneris


  Hairy skin covered pad of fat over the pubic bone
• Labia Minora 


  Small lips covered with modified skin
• Labia majora


  Large lips covered with public hair
• Clitoris


  Small almond shaped erectile tissue located below the junction of two minora
• Vaginally orifice


  Opening into the vagina
• Female reproductive system

  1. Ovaries
  2. Fallopian / Uterine tubeless
  3. Uterus or womb
  4. Cervix
  5. Vagina or birth canal
  6. Vulva
• Parts of vulva

  1. Mons veneris
  2. Labia minora
  3. Labia majora
  4. Clitoris
  5. Vaginal rifice
• Hormones 


  Plays an important role that regulate the function of the entire body or just the specific organ of the body
• Hormones responsible for reproduction

  • FSL (FOLLICLE STIMULATING HORMONE)
  • LH ( LUTEINIZING HORMONE)
• LH 


  Send signals in the testes to produce testosteron
• FSH

  control the production of sperm and the growth of facial hair
• Ova

  Mature egg cells
• Mestruation


  Monthly period, the monthly shedding of the lining of the uterus know as endometrium.
• Endocrine system 


  Paly important role in the menstrual cycle
• Dysmenorrhea

  Severe pain during menstruation
