Placenta helps in the removal of waste material from the foetus as well as protects the foetus against diseases. Justify the statement.

Explanation

### Step-by-Step Solution:

1. **Introduction to the Placenta**: The placenta is a vital organ that forms during pregnancy, establishing a connection between the mother and the developing fetus. It serves multiple functions essential for fetal development.

2. **Removal of Waste Materials**: One of the primary functions of the placenta is to facilitate the removal of waste products from the fetus. As the fetus grows, it produces metabolic waste, particularly nitrogenous waste, which can be toxic if accumulated. The placenta acts as a channel that allows these waste materials to be transferred from the fetal blood to the maternal blood, where they can be excreted by the mother's body.

3. **Protection Against Diseases**: The placenta also serves as a protective barrier between the mother and the fetus. It helps shield the fetus from harmful substances and pathogens that may be present in the mother's bloodstream. This barrier is crucial in preventing infections and ensuring that the fetus develops in a safe environment.
