Final answer:
Abruptio Placentae is more common in multigravida women over the age of 35. It involves premature separation of the placenta from the uterus, unlike placenta previa, which is improper placement of the placenta over the cervix.
Step-by-step explanation:
Abruptio Placentae typically occurs in multigravida women over the age of 35. This condition involves the premature separation of the placenta from the uterus, which can be dangerous for both the mother and the fetus. Risk factors for Abruptio Placentae include advanced maternal age, previous occurrences of the condition, hypertension, and trauma. The process of labor occurs in three stages: dilation of the cervix, the birth of the baby, and delivery of the placenta, which is the afterbirth. In contrast to conditions such as placenta previa, where the placenta covers the cervix, Abruptio Placentae is a separation of the placenta after it has properly implanted in the uterus.
