An embryo is the initial stage of development of a living being before its birth or hatching. In the case of humans, the embryo is formed from the fertilization of the egg by the sperm.
During this stage, the embryo undergoes rapid cell divisions and the formation of basic tissues and organs.
It is a crucial moment in the development process, where the foundations for the future structure and functioning of the organism are established. The embryo continues to develop until it becomes a more advanced fetus and finally a fully formed human being.
