Not using their liver and lung
- Umblical Vein
- Ductus Venousos in baby liver (drops o2)
- Inferior Vena cava
- right atrium
- Right ventricle
- or foraman ovale (connects the atrium) -L Atrium- LV and aorta
- Pulmon. artery (some blood goes to the lungs to help it learn to work but their is major resistance to get blood in there)
- the blood that does not go to the lungs goes thru the ductus arteriousos which goes to the aorta.
Two places where the blood can bypass the lungs.
once the blood bypasses the lungs from blood entering thru the foraman ovale goes to the upper extremities in the blood thru the ascending aorta. once it comes back down goes into the r atrium again. there is always mixed in (babies born blue bc O2 is 80- cause the blood is mixed)
ductus arteriousus- decending aorta- lower extremities illiac arteries, internal arteries then thru umbilical artery to the placenta
