1. when does the fetal heart begin to 3rd week after conception
beat?
2. what fetal shunt connects the um- ductus venous
bilical vein to the inferior vena
cava? allows the majority of highly oxygenated blood to
enter the right atrium
3. the ductus venous allows deoxygenated, right atrium
deoxy-genated/oxygenated
blood to en-ter ?
4. what fetal shunt acts as an
foramen ovale
open-ing between the left +
right atri-um?
blood high in oxygen in shunted to the left
5. when does the foramen
ovale close? atrium after delivery
may take up to 3 months for full closure
6. what fetal shunt connects the
pul-monary artery w/ the ductus arteriosus
descending aorta?
shunts the majority of oxygenated blood to the
7. what happens to the ductus
arte-riosus after delivery? aorta it constricts
in response to the higher blood oxygen levels +
in-
