Descriptor alantoides
Scope note: Saco membranoso extraembrionario derivado del SACO VITELINO de los REPTILES, AVES y MAMÍFEROS. Está situado entre otras dos membranas extraembrionarias, el AMNIOS y el CORION. El alantoides sirve para almacenar residuos urinarios e interviene en el intercambio de gases y nutrientes del embrión en desarrollo.
