The blastocoel is the fluid-filled cavity of the blastocyst that plays an important part in gastrulation later on. The blastocyst is the ball of cells that forms about 5 days after an egg is fertilized. It consists of about 150 cells and has a trophoblast (outer layer), blastocoel (cavity), and inner cell mass, which is an area of about 30 cells that is from where the main structures of the fetus are formed.

When an embryo (fertilized egg) reaches the uterus, it is a hollow ball of about 100 cells called a blastocyst.
What happens to the blastocyst cells that do not become a human body?
They make up the placenta that provides the blastocyst with nutrients.
What is the name for the group of the approximately 100 cells that forms from a fertilized egg?
Blastocyst. Each of those cells will eventually become a different part of the baby's body as they each multiply, creating muscle, bone, and organ tissues.
What is a structure called when the first cell multiplies into a ball like structure?
Blastocyst
What is blastocoel?

Is the degenerating blastocoel visible in the frog gastrula?

What is the central cavity of a blastula called?
blastocoel
What does a blastocoel develop into?
Definitive Yolk sac
What is the cavity within the blastula called?
blastocoel
What is the function of blastocoel?
The blastocoel has two main functions. 1.It permits cell migration during gastrulation. 2.It prevents the animal cells, destined to become ectoderm, from premature induction by the underlying vegetal cells into mesoderm.
