why after childbirth the placenta expelled

Answer 1

After childbirth, the placenta is expelled from the mother's body as part of the natural process called the third stage of labor. This is important for several reasons:

1. Removal of waste: The placenta is responsible for providing oxygen and nutrients to the baby during pregnancy. Once the baby is born, the placenta has completed its function and is considered waste material. Expelling the placenta helps remove this waste from the mother's body.

2. Prevention of infection: The placenta is attached to the uterine wall, and its removal ensures a clean and sterile environment inside the mother's uterus. If the placenta is not expelled, there is a risk of infection.

3. Stopping bleeding: When the placenta separates from the uterus, it leaves behind open blood vessels. The contractions that occur during the third stage of labor help compress these blood vessels, reducing the risk of excessive bleeding.

In most cases, the mother will experience mild contractions after giving birth that help detach the placenta from the uterine wall. The contractions usually cause the placenta to separate and then be pushed out through the birth canal. However, in some cases, medical intervention may be needed to ensure the complete expulsion of the placenta if it does not occur naturally.
