Document Summary

Human sexuality chapter 6: conception, pregnancy and childbirth. In a 28-day menstrual cycle, the woman ovulates on about day 14. The egg is released from the ovary into the body cavity. It is then picked up by the fimbriae (long finger-like structures at the end of the fallopian tube) and enters the fallopian tube. It then begins travelling down the tube towards the uterus, reaching it in about 5 days if it has been fertilized otherwise it disintegrates in about 48 hours. The egg has no means of moving itself and is propelled by the cilia (hair-like structures) lining the fallopian tube.
