Abruption Placenta Anatomy
To better understand placental abruption, it helps to understand the anatomy of the uterus, cervix, and Fallopian tubes.
The placenta is attached to the wall of the uterus. It delivers oxygen and nutrients from the mother's bloodstream to the fetus, during the pregnancy. The normal position of the placenta within the uterus is away from the cervix. The placenta is firmly attached to the wall of the uterus. Bleeding within the placenta can cause the placenta to pull away from the wall of the uterus, resulting in placental abruption.
Anatomy of the female reproductive tract includes:
- The uterus, cervix, and vaginal canal
- The bladder
- The fallopian tubes:
- The ovaries:
- Female organs during a pelvic examination
The fetus grows within the amniotic sac within the uterus:
