The correct path for the removal of waste from the growing fetus is from the growing fetus to the umbilical cord, then to the placenta, and finally to the mother. The placenta plays a crucial role in waste removal, nutrient exchange, and oxygen supply between the mother and the fetus.

Path of Waste Removal from the Fetus
The correct answer to the waste removal process in a fetus is option 'C': Growing Fetus → Umbilical Cord → Placenta → Mother. Here’s a detailed explanation of this process.
1. Waste Production in the Fetus
- The growing fetus produces metabolic waste as it develops. This waste includes carbon dioxide and urea, which are by-products of cellular metabolism.
2. Transport via the Umbilical Cord
- The waste products from the fetus travel through the umbilical cord. This cord contains blood vessels that facilitate the exchange of materials between the fetus and the placenta.
3. Role of the Placenta
- The placenta acts as an interface between the maternal and fetal blood supplies. It allows for the transfer of gases, nutrients, and waste products.
- As the waste-laden blood from the fetus reaches the placenta, the waste is exchanged for oxygen and nutrients that the mother’s blood provides.
4. Elimination into the Mother's Circulation
- Once the waste is in the placenta, it enters the mother’s bloodstream. The mother’s body then processes these waste products, which are eventually eliminated through her kidneys and excreted via urine.
Conclusion
- Therefore, the correct pathway for the removal of waste from the fetus is: Growing Fetus → Umbilical Cord → Placenta → Mother. This process is vital for maintaining a healthy environment for fetal development, ensuring that metabolic waste does not accumulate in the fetal system.
