  • Sperm Enter the Vagina and the Cervix
  • I need to find my friend, and I need to get through the field and most importantly not get lost.
  • Journey of the sperm By: Faith Sexton and Kate Weiler
  • Sperm Travel Through the Uterus fighting the White Blood Cells
  • Oh no, I'm allergic to bees!!! AHHHHH 
  • Run fast so we don't sting you!
  • The Sperm Enters the Doorway - Uterotubal Junction
  • I found the doorway to get to my friend.
  • The sperm enters the vagina and most of them die due to the deadly acids that protect the vagina from pathogens. The cervix usually is plugged shut with mucus to defend against the invading pathogens. The sperm has to navigate and swim single fill through the cervical canal.  Most will either die or get lost and they get stuck.
  • Sperm Makes it into the Fallopian Tube
  • The White Blood Cell army is launched by the body's immune system. The remaining sperm must search for the doorway to the fallopian tube. Muscular contractions of the uterus will help to propel the sperm.
  • Fertiliaztion
  • This is the doorway to the fallopian tube. The sperm must show the proper swimmer characteristics and the correct molecular recognition to be allowed to pass through.   
  • Implantaion
  • Sperm is provided nutrients with nourishment from the fallopian tube so that they may stay alive for several hours, even days.
  • I need to just follow this path and then I'll make it. 
  • The remaining sperm must attempt to find the egg and the upper end of the fallopian tube. The egg is the largest cell in the human body and only lives for 24 hours. Capacitation sheds layers of protein to be able to propel faster in order to penetrate the egg.  Once the sperm is inside the egg and the sperm pair up. If its a girl its (XX) and if its a boy it is (XY). 
  • Friend! I have finally found you!!!! YAYYYYYY
  • The zygote is the union of the sperm and cell that travels down the fallopian tubes towards the uterus, cells begin to divide. Then five days later the embryo breaks out of protective shell and implants in the wall of the uterus and begins growing. 
  • I brought you some seeds so we can plant them!!!
  • Yippie, we will put them in this pot!!!
