But why didnt the baby die if no blood was going through her lungs? Choose the best answer. She was so small that the small amount of blood that did go through her lungs was enough She was getting her oxygen from placenta, not from breathing Before the last trimester, babies use anaerobic respiration, so she did not need oxygen She sent her blood out into her mother's body and through her mothers lungs insteadExplanation / Answer
Before a baby was born she was not sending much blood to her lungs. Instead the blood passed through the septal defect into the left atrium which sent it to the left ventricle and to her body, but why didn't the baby die if no blood was going through her lungs:
The unborn baby does not breathe from it's mother mouth, nose or lungs instead of that the mother’s blood circulates through the placenta and also carries nutrients to the baby. The placenta is attached to the uterine wall and to the umbilical cord, which is attached to the baby. So as the baby does not has well developed lungs it gets oxygen through the placenta, and not from breathing.
