anatomy and physiology of ectopic pergnancy?

Answer 1

An ectopic pregnancy is a condition where a fertilized egg settles and grows in any location other than the inner lining of the uterus. The vast majority of ectopic pregnancies occur in the fallopian tube (95%), however, they can occur in other locations, such as the ovary, cervix, and abdominal cavity.
Infection in the pelvis is another leading cause of ectopic pregnancy. Pelvic infections are usually caused by sexually transmitted organisms, such as chlamydia or gonorrhea. However, non-sexually transmitted bacteria can also cause pelvic infection and increase the risk of an ectopic pregnancy. Infection causes an ectopic pregnancy by damaging or obstructing the fallopian tubes. Normally, the inner lining of the fallopian tubes are coated with small hair-like projections called cilia. These cilia are important to transport the egg smoothly from the ovary through the fallopian tube and into the uterus. If these cilia are damaged by infection, egg transport becomes disrupted. The egg can settle in the fallopian tube without reaching the uterus, thus becoming an ectopic pregnancy. Likewise, infection-related scarring and partial blockage of the fallopian tubes can also prevent the egg from reaching the uterus.

Answer 2

egg is fertilized in the ovary. ovary releases egg in order to transport it through the falopian tubes into the uterus where it's supposed to grow. however the egg gets stuck in the fallopian tube and attaches to the wall there. it starts to grow as it would in the uterus and continues to grow until the fallopian tube bursts and causes internal bleeding into the abdomen as well as death if not caught soon enough.
