Gen Bio 2

• Human reproduction


  Consists of two components - main reproductive organs and accessory organs
• Gonads


  • Testis and ovaries containing germ cells that will give rise to mature sex cells or gametes
• Male and female hormones

  Control the maturity of the reproductive systems and the development of secondary sexual characteristics to prepare the body for reproductive processes
• Male Reproductive System


  • Testis - produce sperm cells
  • Scrotum - pouch-like sac that holds the testis
  • Penis - places sperm into the vagina during mating
  • Vas deferens - transports mature sperm to the urethra
  • Seminal vesicle - secretes one of the components of the semen
  • Prostate gland - secretes a milky fluid that is discharged into the urethra as part of the semen
  • Bulbourethral gland - mucous secreting glands located at the base of the penis
• Female Reproductive System


  • Production of female sex cells
  • Reception of sperm cells from the male
  • Nurturing the development of, and providing nourishment for, the new individual
• Female Reproductive Organs


  • Ovary - produces egg cells
  • Oviduct - passageway of eggs from the ovary to the uterus
  • Uterus - place where fertilized egg develops
  • Vagina - receives the penis of male during mating
  • Ovaries, uterine tubes (fallopian tubes), uterus, vagina, external genitalia, and mammary glands
• The internal reproductive organs of the female are located within the pelvis, between the urinary bladder and rectum
• The uterus and the vagina are in the middle line, with an ovary on each side of the uterus
