external definition

The cavity inside the blastula. [The_evolution_of_organ_systems_(2007)_Oxford:_Oxford_University_Press, p.150, see_Schmidt-Rhaesa_A][VHOG], A blastocoel forms during embryogenesis when a zygote (a fertilized ovum) divides into many cells through mitosis. The blastocoel is the cavity of the blastula, a closed space which is invaded by early mesenchyme and later obliterated by the enlarging archenteron.[AAO]
