Blastocyst - product of cleavage, a ball of cells with a large fluid-filled cavity.
The fertilized egg becomes a blastocyst.
Blastocyst is a pre-embryonic development stage where cellular specialization begins.
After a series of cleavages the morula develops into a blastocyst by the time it reaches the uterus.
If blastocyst implants outside the uterine cavity, it results an ectopic pregnancy.
In the uterus, it attaches to the thickened uterine lining.
