प्रश्न
Does the foetus inside the mother's uterus breathe?
विकल्प
Yes
No
उत्तर
No
Explanation:
During pregnancy, the foetus breathes differently than a newborn. The exchange of gases, including oxygen and carbon dioxide, occurs through the placenta. The placenta transports oxygen from the mother's blood to the foetus, while carbon dioxide created by the foetus is returned to the mother's bloodstream for removal. After delivery, the baby's lungs function, allowing them to breathe.
