Union of a female egg (ovum) with the espermatozoa of the men

0 hours

2-cell

The zygote makes the first cleavage and travells to the endomethrium

30 hours

16-cell

The morula travells to the uterine cavity

3 days

Sperm fertilize the egg by swiming through the fallopian tubes

64-cell

The embryo get to the morula, and then it would develop their outside part, in the interior has a liquid from uterine cavity

4 days

Blastocyst

The morula already develop and convert into a blastocyst ball after 5 days of fertilization

The blastocyst get get to the endometrium to start the development of the embryo

1rst Trim

The hart, some bones, muscles and organs are formed in the embryo, then called fetus

2nd Trim
