do the ductus arteriosis and foramen ovale both shunt blood away from the fetus' lungs, or is it only one that does that?

also, i know the somatic nervous system is both motor and sensory neurons, but what type of neurons, one or both, are in the autonomic nervous system?

thanks guys!

Yes, they both shunt blood from the lungs. I think the foramen ovale does it to the left atrium, and the ductus arteriosis does it to the aorta.

ductus arteriosus shunts from pulmonary artery into aorta
foramen ovale shunts from pulmonary artery into left atrium
ductus venosus shunts away from fetal liver
