Question

ectopic pregnancies result when the zygote implants in the _____, the abdomen, the ovary, or the cervix

Answer 1

Ectopic pregnancies occur when the zygote implants outside the normal location of the uterus, commonly in the uterine tube (tubal pregnancy), and less frequently in the abdomen, ovary, or cervix.

Step-by-step explanation:

Ectopic pregnancies result when the zygote implants in locations outside the uterus, which are not suitable for fetal development. The primary sites of ectopic implantation include the uterine tube, which is the most common location and is referred to as a tubal pregnancy. Other less common sites for ectopic implantation are the abdomen, the ovary, or the cervix. Most ectopic pregnancies occur in the uterine tube, but implantation can also occur on any well-vascularized structure within the abdominal cavity, such as Douglas' pouch, the mesentery of the intestines, and the greater omentum. In rare cases, an embryo can re-implant in the abdomen following a tubal pregnancy.

Answer 2

Ectopic pregnancies can occur in the uterine tube, ovary, or abdomen. In some cases, an embryo from a tubal pregnancy can re-implant in the abdomen. Once in the abdomen, the embryo can implant into various structures.

Step-by-step explanation:

An ectopic pregnancy occurs when a zygote implants outside of the uterus. The three main sites where ectopic pregnancies can occur are the uterine tube (tubal pregnancy), the ovary, and the abdomen. In some cases, an ectopic pregnancy may occur when an embryo from a tubal pregnancy re-implants in the abdomen. Once in the abdomen, the embryo can implant into various structures such as the rectouterine cavity, mesentery of the intestines, or the greater omentum.
