GinnyAnswer

Final answer:

Placenta previa is a condition where the placenta covers the cervix due to low placement of the fetus, leading to antepartum hemorrhage. The growth of placental trophoblasts plays a vital role in this scenario.


Explanation:

Placenta previa occurs when the placenta implants close to the internal os of the uterus, leading to it partially or completely covering the cervix as the fetus grows, causing antepartum hemorrhage. The condition arises when there is low placement of the fetus within the uterus, affecting the location of the placenta. The growth of placental trophoblasts toward the fundus is a key factor in uterine expansion away from the lower uterine segment in placenta previa.
