I like how Alexander Tsiaras showed us about human development from conception to birth and beyond. Even he showed us the development of the fetus in a few minutes, it explained a lot. I wish he explain more in details so we can understand the process of human development from conception to birth better. However, it is amazing to learn and see the development of the fetus, delivery stage, and how women body change after pregnant. I also like when he showed the pictures of fetus heart in 25 or 30 days and how it changes over time or weeks. I was amaze that they use micro-magnetic resonance imaging machine and develop a master piece on the development of the fetus from conception to birth. The pictures and a sample of the piece seems so real.
