Reproductive System

• Reproductive System


  Perpetuation of Species, process of reproduction
• Reproduction


  Biological process by which living organisms produce offspring or new individuals of the same species
• Gametes


  Organism's reproductive cells
• Fertilization


  Process by which two gametes, typically a sperm cell and an egg cell, fuse together to form a new individual organism
• Male Reproductive System


  • Production of Sperm
• Sperm


  Male gamete
• Semen


  Fluid that contains the sperm cell
• Seminal Plasma


  Keeps the sperm healthy and viable
• Penis


  Main male organ for sexual intercourse
• Penis


  1. Root

  2. Body or shaft

  3. Head
• Erection


  Produced when blood flows into the muscles chambers making arousal
• Urethra


  Tube that transports both semen and urine out of the body
• Urethral opening


  Located at the tip of the glans
• Scrotum


  Loose Pouch like sack that holds the testicles
• Testes


  Oval organs about the size of very large olives, main reproductive organ for males
• Spermatic Cord


  Structure that secures the testes
• EPIDIDYMIS


  Carries and stores mature sperms cells, brings maturity to the sperm
• Seminiferous Tubule


  Site for sperm production
• Vas Deferens


  Transports mature sperm, tube that travels from the epididymis into the pelvic cavity
• Seminal Vesicles


  Makes sugar rich fluid (fructose) that provides sperm with a source of energy that helps with motility
• Prostate Gland


  Walnut sizes structure that contributes additional fluid to the ejaculation, fluid nourishes the sperm
• Cowper's Gland / Bulbourethral Gland


  Pea sized structure located on the sides of the urethra, produce a clear slippery fluid that empties directly into the urethra
• Parts of the Sperm cell

  • Head - encloses the nucleus, which carries the male genetic materials
  • Middle Piece - contains the mitochondria that provide energy for the sperm to move
  • Tail - used by the sperm cell for movement
• Spermatozoa


  Mature male gametes in many sexually reproducing organisms
• Spermatogenesis


  Production of sperm cell
• Female Reproductive System


  • Produce eggs to be fertilized, produces female sex hormones that maintain the reproductive cycle, to provide the pace and conditions to allow a baby to develop
• External Parts


  To protect the internal genital organs from infectious organisms and to enable sperm to enter the body
• Labia


  Fleshy folds that surround the opening of the vagina
• Labia


  • Labia Majora - ("large lips") enclose and protect the other external reproductive organs
  • Labia Minora - ("small lips") surround the openings to the vagina
• Clitoris


  Sensitive (bundle of nerves)
• Prepuce


  Covers the clitoris
• Bartholin's Gland


  Produce a fluid (mucus) secretion
• Vaginal Opening


  Menstruation blood, baby, penis during coitus
• Mona Pubis


  Where most pubic hair grows
• Vagina


  Aka as the "birth canal", allows fluid to leave the body
• Uterus/Womb


  Home to developing fetus
• Ovaries


  Produce eggs and hormones
• Fallopian Tube


  Passageway for the ova to travel from the ovaries to the uterus, narrow tubes
• Cilia


  Vital in moving the egg from the fallopian tube to the uterus
• Ampulla


  Primary site of fertilization
