In a similar mechanism to that used by some nematodes, this organ secretes neurokinin B, which allows suppression of the immune system. In Metatheria, the nutrients it supplies are derived mainly from the egg sac. Administration of Rhogam prevents erythroblastosis fetalis, which can be caused by IgG antibodies crossing it. Abruption of it can be triggered by infection or trauma, but is most often caused by high blood pressure. It develops from the trophoblast and produces progesterone, estrogen, and hCG, and failure to remove it after birth can

It develops from the trophoblast and produces progesterone, estrogen, and hCG, and failure to remove it after birth can cause hemorrhaging. For 10 points, name this organ that provides nutrients to developing fetuses through the umbilical cord.
