Week by week

Content: By the time the womb cavity is reached, the cell cluster becomes hollow and filled with fluid; it is now referred to as the blastocyst. A blastocyst is an embryo that has developed to the stage where it has two different cell types: the surface cells, or outer coat, will become – among other things -the placenta that nourishes the baby. The inner cells will become the fetus itself. On contact, the blastocyst burrows into the uterine wall for nourishment; this process is known as implantation. The embryonic stage begins in the fifth week. From weeks five to eight, development is rapid. Major body organs and systems will begin to emerge.
