Before Baby A was born, she was not sending much blood to her lungs. Instead, the blood passed through the septal defect into th
e 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? (A) She was so small that the small amount of blood that did go through her lungs was enough
(B) She was getting her oxygen from placenta, not from breathing
(C) Before the last trimester, babies use anaerobic respiration, so she did not need oxygen
(D) She sent her blood out into her mother's body and through her mothers lungs instead
The correct answer is option (B) "She was getting her oxygen from placenta, not from breathing".
Explanation:
In order to get the oxygen we need to live is necessary that the blood gets through our lungs. If an unborn baby has a problem that does not allow her to get blood to her lungs, she is still able to survive because she could get her oxygen from placenta, not from breathing. Placenta has a respiratory function that allows the baby for fetal oxygen supply and fetal carbon dioxide removal.
Although no two look pups alike, these puppies have inherited genes from both parents and share many of the same characteristics. Organisms grow and develop following specific instructions coded for by their genes. I hope this helps!
