Answer AND Explanation:
Occasionally the zygote fails to move down the oviduct to the uterus but instead gets implanted into the walls of the oviduct where it develops. If the passage of the fertilized ovum is slowed and hatching occurs prior to the ovum reaching the endometrial cavity, the embryo may implant in the fallopian tube. This condition is called ectopic pregnancy. The most common location in the fallopian tube for ectopic pregnancies to occur is the ampulla (70.0%); other locations, such as the isthmus (12.0%), the fimbria (11.1%) and the cornua (2.4%), are less common.
Answer:
PLATO:
The fallopian tube is the most likely place for implantation, because this is the natural path of travel for the sperm. Ectopic pregnancies in different regions of the fallopian tube suggest that the egg gets implanted immediately after fertilization. Abdominal pregnancy is especially unusual, because this is not a normal path for the fertilized egg to take. The cervical pregnancy looks like the fertilized egg transplanted much farther down than normal.
