Document Summary

Egg journey: down the tube toward the uterus, reaching it in about ve days if it has been fertilized. The egg, unlike the sperm, has no means of moving" itself and is propelled the cilia (hairlike structures) lining the fallopian tube. The egg has begun its part of the journey toward conception. The woman"s cervix secretes mucus that ushes the passageways to prepare for the arrival of the sperm. Where does conception occur: occurs typically in the outer third (the part near the ovary) of the fallopian tube. Attractant chemical: a chemical secreted by the egg attracts the sperm to the egg. Chemical receptors on the surface of the sperm respond to the attractant, and the sperm swim toward the egg. Zygote: the developing organism from the time of the union of the sperm and the egg to about the second week of gestation: continues travel down the fallopian tube.
