Answer :
The blood-rich structure that serves as a lifeline for the developing fetus is called the placenta.
The placenta is an organ that forms during pregnancy and connects the developing fetus to the uterine wall of the mother. It acts as a vital interface between the mother and the fetus, allowing the exchange of nutrients, oxygen, and waste products.
The placenta develops from the fertilized egg and contains blood vessels from both the mother and the fetus. Maternal blood flows through the placenta, delivering oxygen and nutrients to the developing fetus, while fetal waste products, such as carbon dioxide, are removed through the placenta and into the mother's bloodstream for elimination.
The placenta also plays a crucial role in hormone production, producing hormones such as human chorionic gonadotropin (hCG), progesterone, and estrogen, which are essential for maintaining pregnancy and supporting fetal development.
Overall, the placenta acts as a lifeline, providing the necessary nutrients, oxygen, and waste removal for the developing fetus, while also facilitating hormonal regulation throughout pregnancy.
