Etymology: Gk, blastos, germ, koilos, hollow

the fluid-filled cavity of the blastocyst in mammals and the blastula or discoblastula of lower animals. The cavity increases the surface area of the developing embryo to allow better absorption of nutrients and oxygen. Also spelled blastocoel, blastocele. Also called cleavage cavity, segmentation cavity, subgerminal cavity.

blastocoele

The cavity formed within the mass of cells of the blastula of many animals during the later stages of cleavage.

The increase in oxygen consumption coincident with blastocyst formation is thought to reflect an increased metabolic demand generated by the pumping of sodium and potassium ions that drives the enlargement of the blastocoele (9).
