An embryo makes blood because it begins to develop into a fetus and later into a new infant. An egg can not become an embryo without the DNA that the sperm donates.
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )

Once the zygote becomes an embryo it starts developing all of its organs, nervous system etc. then after 8 weeks of development everything is there so it becomes a fetus, and the fetus just grows bigger.
