Question

Quizplus · Accepted Answer

The allantois does not act as the fetal bone marrow. It is a membranous sac that develops during embryonic development and connects the developing embryo to the placenta, playing a role in gas exchange and waste elimination. While it does store nitrogenous wastes, partially derives from endoderm, and part of it will develop as the urinary bladder, it does not have any role in fetal bone marrow production.
