Final answer:
The placenta performs several important functions including nutrient and gas exchange, hormone production, and protection.
Step-by-step explanation:
- Nutrient and gas exchange: The placenta allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus. It acts as a filter, ensuring that harmful substances do not reach the fetus.
- Hormone production: The placenta produces hormones like human chorionic gonadotropin (hCG), estrogen, and progesterone. These hormones are essential for maintaining pregnancy and supporting fetal development.
- Protection: The placenta provides a physical barrier that protects the fetus from infections and some harmful substances in the mother's bloodstream.
