Final answer:
An Ectopic Pregnancy refers to a pregnancy where the embryo develops outside the uterus, commonly in the fallopian tubes, and poses serious health risks.
Step-by-step explanation:
The diagnostic term Ectopic Pregnancy actually refers to a pregnancy in which the embryo implants and starts to grow outside the uterus, most commonly in the fallopian tubes, which is then referred to as a tubal pregnancy.
Other less common sites for ectopic implantation include the ovary, known as an ovarian ectopic pregnancy, or in the abdominal cavity, known as an abdominal ectopic pregnancy.
In ectopic pregnancies, a fertilized egg fails to reach or implant in the uterus for development, which poses serious health risks to the mother and is not viable for the fetus.
