The placenta is a vital organ during pregnancy. It develops inside the uterus and connects the mother to the baby through the umbilical cord. This organ starts forming soon after the embryo implants in the uterus. It acts like a bridge, allowing the baby to get nutrients and oxygen from the mother’s blood. At the same time, it helps remove waste products from the baby’s bloodstream.
The placenta also produces important hormones, such as progesterone and estrogen, which help the pregnancy progress smoothly. These hormones maintain the uterine lining and support the baby’s growth. By acting as a filter, the placenta keeps harmful substances from reaching the baby, although it does not block everything. Drugs, alcohol, and certain infections can still pass through and affect the baby’s health.
Placenta: Lifespan and Delivery
The placenta continues to grow throughout pregnancy, adjusting to the baby’s needs. Around the 12th week of pregnancy, it takes over the job of hormone production from the ovaries. This ensures that the pregnancy stays stable.
As the pregnancy comes to an end, the placenta prepares for delivery. After the baby is born, it detaches from the uterine wall. The mother’s body then expels it, which is often called the “afterbirth.” Doctors or midwives check to ensure it was delivered fully. If pieces remain inside, it could cause infection or other complications.
The placenta’s health directly impacts the baby’s development. Issues like placental abruption, where the placenta detaches too early, or placenta previa, where it covers the cervix, may require medical attention. Both can pose risks to the mother and baby if not treated in time.
Understanding the placenta’s role helps expectant parents appreciate its importance in ensuring a healthy pregnancy and birth.
