FAQs on Placenta - Medical Science Optional Notes for UPSC

1. What is the function of the placenta during pregnancy?
Ans. The placenta is an organ that develops during pregnancy and serves several important functions. It provides oxygen and nutrients to the developing fetus, removes waste products from the fetus, and produces hormones that support pregnancy.
2. How does the placenta form in the uterus?
Ans. The placenta forms when the fertilized egg attaches itself to the uterine wall. Specialized cells from the embryo called trophoblasts invade the uterine lining and establish connections with the maternal blood vessels, creating a network of blood vessels that supply nutrients and oxygen to the growing fetus.
3. Can problems with the placenta affect the health of the baby?
Ans. Yes, problems with the placenta can have significant effects on the health of the baby. For example, if the placenta does not develop properly or detaches from the uterine wall prematurely, it can result in restricted fetal growth, low birth weight, or even stillbirth. Certain conditions, such as preeclampsia or placental abruption, can also arise due to placental problems and pose risks to both the baby and the mother.
4. What are some factors that can increase the risk of placental abnormalities?
Ans. Several factors can increase the risk of placental abnormalities. These include advanced maternal age, smoking, drug use, certain medical conditions (such as diabetes or high blood pressure), multiple pregnancies (such as twins or triplets), and a history of previous placental problems.
5. Are there any measures to ensure a healthy placenta during pregnancy?
Ans. While it is not possible to guarantee a completely problem-free placenta, certain measures can help promote a healthy placenta during pregnancy. Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding harmful substances like tobacco and drugs, can contribute to optimal placental development. Regular prenatal check-ups and monitoring can also help detect any potential issues early on, allowing for proper management and intervention if necessary.
