Why do babies need the blood from mother?

Babies don't actually need the blood from the mother in the way you might be thinking. The blood of the mother and baby never directly mix.

However, the placenta, which connects the baby to the mother's uterus, acts as a filter and exchange system. Here's how it works:

* Oxygen and Nutrients: The mother's blood carries oxygen and nutrients. These pass through the placenta and into the baby's blood.

* Waste Removal: The baby's blood carries waste products like carbon dioxide. These pass through the placenta and into the mother's blood, where they are removed by her body.

* Antibodies: The mother's blood also contains antibodies, which help protect the baby from infections. These antibodies pass through the placenta and into the baby's blood, giving the baby a temporary immunity boost.

So, while the blood doesn't directly mix, the placenta allows for a critical exchange of essential substances between mother and baby, ensuring the baby's healthy development.
