Final answer:
Abruptio placentae is the condition in which the placenta partially or completely separates from the uterine wall. It can lead to bleeding and requires immediate medical attention.
Step-by-step explanation:
The condition in which the placenta either partially or completely separates from the uterine wall is called abruptio placentae. This occurs when the placenta detaches before the baby is born, leading to bleeding and potential complications for both the mother and baby. It is important to seek medical attention if abruptio placentae is suspected, as it requires immediate care.
