Maternal ABO IgM antibodies crossing the placenta to lyse fetal red blood cells

Fetal cytotoxic T cells targeting maternal syncytiotrophoblasts

Direct complement activation by maternal IgA secreted into amniotic fluid

Junction of the left internal jugular and left subclavian veins

Junction of the right internal jugular and right subclavian veins

Superior vena cava at the level of the azygos vein entry

Inferior vena cava directly above the diaphragmatic hiatus

Which enzyme catalyzes the final step of the coagulation cascade, converting soluble circulating fibrinogen into insoluble fibrin monomers?
