When you’re expecting, your healthcare provider doesn’t just monitor your baby’s growth during ultrasounds; they’re also observing the placenta, a vital organ that supports your baby’s development.
What is the placenta?
The placenta is a disc-shaped organ that forms solely during pregnancy. Composed of blood vessels, it serves as a lifeline for your developing baby, supplying essential nutrients, water, oxygen, and antibodies while also facilitating waste removal. The placenta adheres to the uterine wall and is connected to your baby through the umbilical cord, sharing the same genetic material. Typically, a single placenta supports each baby; however, if you’re expecting twins, each may have its own placenta.
What functions does the placenta serve?
This remarkable organ performs several crucial functions, including nutrient transfer, gas exchange, and immune protection. It acts as a barrier, thereby shielding the fetus from some infections while allowing necessary substances to pass through. The placenta also plays a role in hormone production, which helps maintain the pregnancy.
When does the placenta form?
The placenta begins to develop shortly after conception, starting from the fertilized egg’s implantation into the uterine lining. By the end of the first trimester, it is generally well-formed and fully functional.
When does the placenta take over?
Around 10 to 12 weeks of pregnancy, the placenta takes over the role of producing hormones necessary for sustaining the pregnancy, previously managed by the corpus luteum.
Where is the placenta located?
The placenta is found within the uterus, attached to the uterine wall. Its position can vary, and it can be located in different areas, including the front or back of the uterus.
How much does a placenta weigh?
Typically, a placenta weighs about 1 to 2 pounds at the end of pregnancy, but this can vary depending on individual circumstances.
Potential placental complications
While most pregnancies proceed without issues, some complications can arise, such as placental abruption or previa. Monitoring and proper prenatal care are essential for addressing any concerns.
Delivering the placenta
After childbirth, the placenta is delivered, usually within a few minutes to half an hour of the baby’s birth. This process is often referred to as the third stage of labor.
