Question

How does the embryo get nourishment inside the mother’s body? Explain briefly.

Answer 1

Step 1: Formation of placenta
After fertilization, the embryo gets implanted in the uterus wall where a special tissue called the placenta develops.

Step 2: Connection between mother and embryo
The placenta contains blood vessels from both the mother and the embryo. However, their blood does not mix directly.

Step 3: Exchange of nutrients and gases
Oxygen and nutrients such as glucose and amino acids from the mother's blood pass through the placenta and reach the embryo.

Step 4: Removal of waste products
Waste materials like carbon dioxide produced by the embryo pass back through the placenta into the mother's blood for removal.

Step 5: Role of placenta
Thus, the placenta acts as a transport system, ensuring the embryo gets nourishment and stays healthy during development.
