D, E, F
Feedback:
The placenta supplies the developing organism with food and oxygen, carries waste away for excretion by the mother, slows the maternal immune response so that the mother's body does not reject the fetal tissues, and produces hormones that help maintain the pregnancy. Wharton's jelly protects the umbilical cord and the foramen ovale permits most of the blood to bypass the right ventricle. The amniotic fluid cushions the fetus against injury.
