Identify the foeto-maternal organ

Options

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

Answer

To identify the foeto-maternal organ from the given options (embryo, uterus, placenta, and blastocyst), we can follow these steps:

### Step 1: Understand the Options
- **Embryo**: This is the developing organism but not an organ.
- **Uterus**: This is the organ where the embryo develops but is not specifically a foeto-maternal organ.
- **Placenta**: This is the organ that connects the mother and the fetus, facilitating the exchange of nutrients and waste.
- **Blastocyst**: This is an early stage of the embryo but does not function as a foeto-maternal organ.

### Step 2: Identify the Function of Each Option
- The **placenta** serves as a barrier and interface between the mother and the fetus. It allows for the transfer of oxygen and nutrients from the mother to the fetus and the removal of waste products from the fetus to the mother.
- The **uterus** provides a nurturing environment for the embryo but does not directly facilitate the exchange of substances.
- The **embryo** and **blastocyst** are stages of development and do not function as organs for maternal-fetal exchange.

### Step 3: Conclusion
Based on the functions and definitions:
- The **placenta** is identified as the foeto-maternal organ because it plays a crucial role in connecting the mother and fetus, facilitating nutrient and waste exchange.

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