Does fertilization occur in the uterine tube?
Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
Where does fertilization of an egg occur quizlet?
Egg is fertilized in the Fallopian tube. It takes 3-4 days for the egg to get to the uterus. The fertilized egg (zygote) is called an embryo after it is implanted in the uterine lining.

Besides the cells that secrete fluids, the mucous membrane contains cells that have fine hairlike structures called cilia; the cilia help to move the egg and sperm through the fallopian tubes.
How is an egg fertilized?
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus.

Why must fertilization occur in the fallopian tube before the ovum moves into the uterus?
Contact Between Sperm and Oocyte. Upon ovulation, the oocyte released by the ovary is swept into—and along—the uterine tube. Fertilization must occur in the distal uterine tube because an unfertilized oocyte cannot survive the 72-hour journey to the uterus.
When fertilized egg is implanted in the uterus?
Implantation. Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. In nature, 50 percent of all fertilized eggs are lost before a woman’s missed menses.
