Options

A. Embryo
B. Uterus
C. Placenta
D. Blastocyst

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Foeto-maternal Organ":**
- The term "foeto-maternal organ" refers to an organ that facilitates the connection between the fetus and the mother during pregnancy.

2. **Identifying the Organ:**
- The key organ that connects the fetus to the mother is the placenta. It is formed from the chorionic villi that develop from the embryo and invade the uterine wall.

3. **Function of the Placenta:**
- The placenta serves several critical functions:
- **Gas Exchange:** It allows for the exchange of oxygen (O2) from the mother to the fetus and carbon dioxide (CO2) from the fetus to the mother.
- **Nutrient Transfer:** Nutrients from the mother’s blood are delivered to the fetus through the placenta.
- **Waste Removal:** Waste products produced by the fetus are transferred back to the mother’s circulation for disposal.
- **Hormone Production:** The placenta produces hormones such as human chorionic gonadotropin (hCG) and human chorionic somatomammotropin (HCS), which are vital for maintaining pregnancy and supporting fetal development.

4. **Conclusion:**
- Based on the functions and the definition of the foeto-maternal organ, the correct answer to the question is the placenta.

**Final Answer:**
- The foeto-maternal organ is the **placenta**.
